Between one and three percent of twins have different fathers. Technically you could get a girl pregnant while she is pregnant. It would have to be hours after the first baby was conceived. Far more common in dogs than bitches.
You can not get her pregnant if she already is pregnant...sorry that's erroneous...and idiotic!! Uterus goes through too many changes due to hormone levels that are sky high in pregnancy. Have you ever seen a female give birth then...oh shit... 3 weeks later she's having another one?
It's called superfetation and is extremely rare in humans for three reasons: 1) A woman does not normally ovulate when she is pregnant. 2) When a woman is pregnant, a plug of mucus forms in the cervix preventing sperm and other pathogens from entering the uterus. 3) A fertilized egg must implant itself in a uterus that is already occupied and nurturing developing baby with a different set of hormones.
