is she pergo?

usually it will take a girl anywhere from 1-3months to get back to a regular cycle and be able to become pregnant. and also just because you have unprotected sex doesnt automatically mean you will become pregnant. women are only fertile a couple of days out of the week. usually day 14 of the cycle counting day 1 as the first day of your period. but some ovulate early and some ovulate late depending on their cycle. So I highly doubt it.
