It's VERY possible. Especially if you allowed for the majority of his, umm let's call them baby makers, to stay inside you (as in not standing up shortly after the deed was done and not wiping down there)
@Breaha does not wiping down there help the sperm reach where it needs to?
@Isha Well, if it's a thorough wipe, a good amount will be removed, but obviously a lot will still be further inside so of course pregnancy can still happen. But if no wiping is done then the majority are definitely going to still be inside, especially if a woman lies down.
My first pregnancy took 2 years my second pregnancy took 1 time lol so it could be very likely
