A/N: This is the sequel to 'Under the moonlight'. I decided to start this as a new entry as I wanted to leave the first story open for other possibilities.

Stomach pains

Vegeta groaned as he dragged himself up this morning. He reached over Bulma's side, but where was the woman… she couldn't have gotten up before him. He snatched the alarm clock… 8 am?! What the hell… he had never woken up this late before… It wasn't going to be a good day, he could already tell.

His muscles protested the moment he straightened himself out, as he set his feet on the floor. Every joint strained as though he had not used them for some time. That was unlikely, he had trained most religiously; likely he must have overdone it. Still this ache was not of familiarity; not one he would associate with the usual strain he was used to enduring after hours of intense training.

His body ached; in his joints and especially his back. He was feeling exhausted despite the extra hours he snoozed; and his stomach… he needed the bathroom badly. Clearly his stomach hadn't agreed with his choice of food last night.

…

"Are you alright?" Bulma watched as Vegeta picked at his food; for the 3rd time in the course of 2 days. She watched as he avoided the bacon and orange juice, taking 5 plates worth of pancakes, the whole jug of syrup and the carton of milk…. Not only was he suddenly picky about his choice of food. He wasn't eating as much as before.

"I'm fine" Vegeta stabbed at the last bite of pancake, drowning it in syrup before shoving it into his mouth; he was done. This had gone on for 2 days now, the sudden fatigue, drop in appetite, the pain in his joints and back and the unusual sensation in his stomach.

He frowned, pressing a hand to his stomach; feeling uncomfortable as another wave hit him. He hadn't eaten much, as far as Saiyan dietary standards went and yet he was feeling bloated as though he had cleaned out a buffet feast, on top of breakfast and lunch.

"Don't you start coddling me, Bulma. I'm fine" he knew that look she was throwing his way and frankly, he didn't want to deal with it.

"Don't give me that, Vegeta. Your appetite's changed; you've been dragging yourself out of bed for the past 2 days, along with other symptoms I haven't begun to describe. Need me to go on?"

Vegeta groaned as she started it anyway. "For the last time, woman. I'm fine"

"No, you're not mister" Bulma crossed her arms, tapping a finger as she did. Great… Now she was addressing him like she did Trunks years ago. A very young, stubborn Trunks aka… a child.

"It's nothing. My stomach has merely decided to take my gut along with the rest of me hostage until certain demands are met. It will pass, now would you stop fussing over me" not bothering with the glass, he drank the milk from its carton.

"Still, I want you to get yourself checked out all the same. If you're not worried I am, Vegeta… I can do a quick examination… just to be sure you didn't catch what Goku once had"

"That was a heart virus, woman and according to Saiyan anatomy; that particular organ doesn't reside in my smaller intestines.

"Very clever. It could be a stomach flu or some other virus we don't know of and you may need medication for that" Bulma wasn't going to back down. That stubborn jerk wouldn't seek out aid for himself, even if he was bathed in blood.

"I'll let you know the moment my stomach decides to start sneezing" Vegeta knew what she was talking about, still he couldn't resist riling her up; it was fun. He smirked as the calm façade about her started to crumble before adding… "I can take care of myself Bulma. You'll be the first to know if otherwise" and watched as she 'deflated', unsure if she should still go ahead and say what she would have said if he hadn't added that last bit in.

"Jerk" but she smiled when he smirked in her direction. "Make sure you do or I'll nag you till your ears bleed"

"Hn"

Bulma came closer, pressing herself against him as she ran her fingers along his arm. "Or you could find other ways to make me 'sing', I think we both know a song that has your name in it. Trunks' at school and Bra's gone out with my parents" Then just as quickly she moved away, unable to resist a smirk at the sight of his irritated face.

Oh Vegeta knew where this was going, that scheming woman. He pushed back the purr and settled for a growl as Bulma started walking slowly out the kitchen. His pants becoming tighter as she played a little game of peek-a-boo, lifting her skirt up a little higher; showing him just a little but barely enough! His eyes followed her, from her thigh… to her face, settling on her finger as she extended her index finger out. He swallowed as she crooked her finger, beckoning him to follow.

"You'll have to earn what you receive, Vegeta. We won't have it any other way" she winked as she disappeared from his view.

"Vile, conniving woman" he spoke without conviction, putting down the milk as he followed her out of the kitchen.

Thursday and he still hadn't felt better.

Vegeta grumbled as he felt another sharp pull in his lower abdomen. Damn it, what the hell was wrong with his blasted stomach. 3 days and the discomfort still wouldn't leave him. Worse, it wasn't just uncomfortable now… there was definitely pain as well.

"Hey Vegeta! You ready?" Goku IT'ed himself in as was his usual practice every Thursday for their weekly spar.

"Fuck! How many times do I have to tell you to use the goddamn door?!" Vegeta glared, easily irritated now more than usual.

"Ah gomen, gomen" Goku apologised, rubbing the back of his head as Vegeta pinched the bridge of his nose in an effort to take off some of the tension he felt. "So are you up for a spar?"

~Growl~

Goku rubbed his stomach, looking at Vegeta with a sheepish grin. Vegeta rolled his eyes in respond, indicating with his thumb towards the door for Goku to go find Bulma or raid the fridge himself.

"Great! I won't be long" Goku instantly left for the kitchen.

…

"Son-kun" Bulma smiled as Goku entered the kitchen.

"Yo Bulma" he waved, Bulma knew what he was looking for.

"Help yourself. There's plenty to go around" more than plenty in fact, Vegeta hadn't eaten much again today. She sighed as she made herself a cup of coffee.

"What's wrong, Bulma?" Goku looked up, having heard her sigh; his cheeks stuffed with food.

"It's Vegeta… being stubborn" She set her cup down as she sat in front of Goku.

"Eh? How is that something different?" Goku crooked his head, thinking hard… Vegeta had always been stubborn and difficult after all… this was hardly new.

She snickered. "I guess that's true. He's always been so pigheaded" she sighed again. "Son-kun, later when you two spar… could you just, you know monitor him? I don't know what's wrong with him but he hasn't been well for a few days now. He won't listen to me, but if push comes to shove. I would need you to bring him here, maybe even hold him down so I can have a look at him"

"Ah I don't think he's going to like that, Bulma…" Goku could pretty much imagine how that would turn out.

"I know Son-kun. And I don't like doing that to him or asking this of you. But ultimately, I want what's best for him, for his health and all. I'm sure you do too" Bulma looked at Goku, asking if she was right with eye contact alone. A nod from Goku and she nodded too. "If it comes to that son-kun… then we'll have to steel ourselves. For his own good" she looked at him, steadfast and he narrowed his eyes, nodding again.

He would bring Vegeta back, kicking and screaming if he had to. If there was indeed something ailing Vegeta, then he would make sure he got the treatment he needed… thing was... what was ailing him anyway…

Goku hovered above, watching the crater Vegeta had just crashed into; waiting for the smaller Saiyan's counter attack.

Goku had to agree Vegeta wasn't himself this week. The man was slow, distracted every so often, his aim was off and his ki was irregular. Goku gave him 2 minutes to emerge before deciding to go get him himself. He landed beside the crater, removing the debris from Vegeta's person; supporting him with an arm around his waist.

"Ch! I'm not done yet, Kakarotto!" he pushed Goku, standing upright some distance from him as he steadied himself; wiping the sweat, blood and dirt from his brow.

Goku was not convinced, he could feel it in his bones. Vegeta was exhausted.

He was shocked, they had not fought long enough nor had they gone Super Saiyan 2 yet the smaller man in front him was near done. Bulma was right, something wasn't right with him. This theory proven right when Vegeta bend over, clutching his stomach in an obvious show of pain.

"Vegeta!" Goku once again caught hold of him, becoming increasingly worried when he saw the pain reflected on Vegeta's face. "What's wrong!?"

"Fuck!" Vegeta panted, the pain pulling at him so harshly he could barely stand, despite his best efforts to. The signs reminded Goku of something… oh god no…

"Vegeta! It's the heart virus, isn't it!? I'm taking you back to Bulma now!"

"It's not baka!" Goku was deaf to Vegeta's explanation. Quickly, he grabbed Vegeta to him; pressing two fingers to his temple. Both men blinked out of existence, back at Capsule Corps again.

Back at the lab, Bulma took a sip of her coffee as she put the final touches to her latest invention, a rather delicate piece of machinery… slowly, steady… she could not afford one mistake.

"Bulma!" An unexpected shout behind her and she shrieked, dropping her tools and everything around her in the process.

"Son kun?" she turned. "Vegeta!? To the infirmary, quickly!" she rushed out, trusting Goku to follow her; he did, keeping up with her easily. He brought Vegeta in just as Bulma opened the door for them, gently lowering him onto the op table.

Vegeta hissed, still clutching to his stomach.

"You got to help him, Bulma. I think he's got that heart virus" Goku turned to Bulma intending to explain his suspicion when a curse brought his attention back to Vegeta.

"For the last time, Kakarotto… It's not! It's my fucking stomach and I know I didn't drop my heart in there!" Vegeta steadied himself, propping himself up from the table with an arm.

"Don't get up, Vegeta. Even if it's not, you should let Bulma take a look" Goku tried to get him to lay down again. Forgetting his own strength as he pushed him back down, slamming him onto the cold, hard table; head, back and all.

"FUCK! Kakarotto!" he brought a hand behind him, rubbing his now aching head.

"Gomen Vegeta! I didn't mean it! Here!" Goku quickly brought over a pillow for Vegeta, sliding it under his head for him.

"It's your stomach again? No more arguing with me, Vegeta. I'm giving you that examination today and before you start arguing with me, know that I will not allow you to slide this one on me"

"Woman, I said I'm fine! I don't need you to probe me like I'm…" he didn't get to finish his sentence as Goku started sniffing him. "What the hell are you doing, baka!" he pushed Goku's face from him.

"I smell blood on you…"

"Of course you do, idiot! We were just sparring moments ago!"

"No. It's not that… it's fresh…" Goku shook his head, determined to find the source… then without warning. He turned Vegeta to his side, pulling the spandex and underwear down.

"Ahh! What the fuck! Kakarotto!?" Vegeta twisted his body to face him, about to smack him for that when he noticed Goku's eyes widened in what akin to horror.

"Son-kun?! What are you doing!?" Bulma was just as speechless until she noticed that look as well. She came forward, then covered her mouth with a hand as she saw what he did.

"What!?" Vegeta looked from Bulma to Goku and back again.

"You're bleeding… there's blood on your underwear"

"It's the norm that I'm covered in my own blood from head to toe every week and during the occasional enemy clashes on Earth and yet you're both horrified over some spots on my underwear?!" Vegeta clutched his stomach when another pull hit him.

"Son-kun, I'll need your help. We better do a proper examination, the sooner the better" Bulma tried to stay as calm as she could.

If it was serious, she would assume it would be something similar to stomach ulcer that if left untreated, could result in death for humans. She hoped she was wrong, and that it would be something else like a small anal fissure or maybe hermorrhoids… something that the Saiyan body could heal itself in no time. But if it was something unknown… like the circumstances surrounding Goku's heart virus, saved only because of Mirai Trunks' intervention… she quickly pushed that thought out of her mind, setting to work while Vegeta was still feeling 'co-operative'; he would not remain that way for long.

...

"Satisfied? Or would you like to turn me inside out just to be sure?" Vegeta directed his anger towards Goku, muttering the word 'traitor' under his breath.

"But Vegeta..." Goku sighed, there was no point trying to explain to him.

"I asked him, Vegeta and it's for your sake" Bulma explained.

"Hn. Well?" Vegeta crossed his arms, focusing his attention on her in favour of ignoring Goku. Waiting for Bulma to give her readings; he would never admit it but he was anxious to know as well... but just a notch. What was causing him discomfort for 3 days and might continue for Dende knows how long. What unknown virus could be devastating, if not fatal to a Saiyan.

"According to this... there's nothing wrong with you. Which is a big relief... but your iron levels are low right now... which is very strange..." Bulma raised an eyebrow at the results.

"Why strange?" Goku asked.

"Because such reading aren't usually found in men... but at least it's nothing that can't be remedied. A few iron tablets and you'll be good to go. An explanation I could come up with for your pain, would be due to something you ate and as for the bleeding..." she raised an eyebrow at those two, missing the sudden still of breath they held. "Maybe you've both been too rough on your spars so there might be some leftover injuries from before and you're only showing them now... or you could have accidentally tore your rectum walls when you visited the bathroom"

She walked towards the table, opening a small compartment, returning a moment later with two tablets in hand. "Here. Take these"

Vegeta turned up his nose at the smell. "Whatever for. I'm a Saiyan"

"Well I'm aware of that but you need these, Vegeta. They're just iron tablets, to replenish your blood cells" she held the tablets out, in front of him.

"A Saiyan's body will heal itself, faster than a human. I have no need for that" he stubbornly refused to take the tablets.

"You might be willing to wait it out in pain for your body to recover itself, but I'm not" Bulma was reminded of the time he trained for the androids' arrival. How he had made her worry... the many times he came close to death...

It was a time she didn't want to return to, the other being his 2nd death when he had sacrificed himself in a fight with Majin Buu. It brought back too many old ghosts.

"Alright, if you won't take them. Then I guess I can't force you" Bulma placed the tablets, along with the glass of water on the table beside him. Vegeta met her eyes, she was up to something; it wasn't like her to yield.

Goku watched as she returned to the table, opening the same compartment; searching for something... Immediately he paled as he saw her bring out a syringe, a very big syringe! Vegeta's eyes widened as well.

"What the hell is that for, woman?!"

"Ever heard of suppositories, Vegeta? Well this is what the syringe is for... now to find something to grind the tablets into powder... then I can mix it with some water..." she busied herself, giving the illusion that she was indeed looking...

"You will do no such thing!" Vegeta growled, ready to sprint.

"I really hate to do this to you Vegeta, but it's for your own good and since you won't take them... I have no choice. I'm sorry to have to ask you to help me again. Son-kun"

Vegeta immediately turned his attention to the Saiyan beside him.

"Gomen, Vegeta... but it's for your own good..." Goku looked just as apologetic as he was earlier. SHIT!

Quickly, Vegeta snatched the 2 tablets on the table; popping them into his mouth before swallowing the water in the glass. Done! He slammed the glass back on the table.

"Oh. I guess we won't be needing this after all" Bulma smiled as she kept the syringe, pleased with herself.

"Evil woman..." he grumbled under his breath.

3 months later...

"Hey Vegeta?"

"What...?" Vegeta leaned back, resting against Goku as he sat comfortably in between the other Saiyan's legs, in front of him. Enjoying the calm serene as he had on this very cliff every month, savouring the cool breeze that caressed his naked skin after another night of activity.

"You're fine now? No more pain?" Goku gently rested his chin against the Saiyan prince's head.

"Don't remind me. I'm fine now"

"You know Vegeta... I think... that time... maybe I was too rough? Maybe that's why you bled?"

"What did I just say, Kakarotto. I don't want to talk about it, this would make it close to 3 months since that day and it hasn't happened again. Drop it" Vegeta had considered that possibility, but it was highly unlikely... considering the drama started days after they've screwed.

There was another reason, one, he neglected to tell anyone... he had noticed the same blood spots on his underclothes again... just 5 days back, it lasted for about 3 days; the previous one around 3 as well. He had removed all traces of evidence, washing the blood stains himself, not wanting to be subjected to Bulma's tests again. The pain; a mild, pulling ache this time, enough for him to hide his discomfort.

Whatever. It's over.

"Ok ok..." Goku hugged him as he always did on such nights, nuzzling his prince; loving every moment of it.

…

Deep inside Vegeta's body, another ovarian follicle was starting to develop, preparing the next stage, Ovulation... waiting as the body restarted the process of releasing a single, mature egg...

To be continued ~

Well... 'Under the moonlight' was supposed to be a one-shot, but since I had so many requests for it to be continued… I'll give it a go. I just knew I couldn't do a one-shot properly.

I had to do quite a bit of research on this topic, even study a little bit on human anatomy... and I still don't have much of a clue. I decided to try my hand on mpreg, since I've already written a genderbender fic before. Feedbacks anyone?

As always I hope everyone enjoyed this.

Don't forget to tell me what you think, have a great day everyone~ XD
