I actually know someone with two uteruses. She was pregnant in high school and opted for an abortion. When she was still pregnant afterwards, they discovered two uteruses. No joke.
I'd probably opt for the pill.
Two uterus?? Wow, I didn't know such a thing was even possible. I guess condoms or the birth control pill...a barrier method prevents sperm from entering at all, so thats why I would think condoms, and the birth control pill or depo shot controls hormons, so if should work as well.
Lol, I know I will be checking this out on the internet...how can that be?
Good luck to your niece.
