Idk man yaoi magic
I saw this detailed af yaoi thing where the guy was looking inside of the omega with tools you use for women and it showed where the uterus is connected and such-- And--It was high detailed I THINK. . .
First about ovaries and uterus : I think it's like omegaverse ... If you read omegaverse most of them have explanations of people's body ...
Second the menstrual cycle question: for omegaverse it's the "Heat" , but in one of the manga I read I remember about the omega leaking down there (not blood) .. so we can say it's based on the author.
Best answer tbh hahahaha
I've always been very confused about the mpreg stuff. How does the..egg? get fertilized? I don't think feces would be very healthy for sperm to travel through. Especially this where he was like a magicafied birth giver, did he just grow ovaries and a uterus???? Would he also have a menstrual cycle? I feel like omegaverse and mpreg tropes really gloss over this stuff.
