Nah, if you want the full explanation you can easily google it but the short answer is: no, they can't get pregnant/they don't get their period.
Just search for hermaprodite if you wanna know ;)
But, I you remember, his is he world of anime and manga, here everything can happen (I know that in real life is impossible, don't worry)
This* the*
yes some can get pregnant, some can't. Hermaphrodites have both functioning uterus, ovaries and testicles. So they could get pregnant. However this is not the case for everyone. Its like how there is still some infertile cis women. each body is different. So we can;t say it is impossible. Even men could get pregnant if they had a uterus. Who knows? Everyone is born differently
Wait so uke is born with two sexes, does that means its possible for him to get pregnant and having a period? That will be really hard if ya gonna ask me (￣∇￣")
