Okay, sorry for the bad info part
It's entirely dependent on your body and when you ovulate. Is it possible to get pregnant on your period? Yes. Is it possible to get pregnant while on b/c? Yes. Wait two weeks from the last time you had sex and take an hpt.
You can NEVER be to sure...A friend of mine got pregnant for both of her children while on her period...it's not common and rarely happens and you are most definitely NOT more fertile on your period, but it is possible...Your best bet is to wait it out over the next couple weeks then all you really can do is take a pregnancy test...
That is NOT true. You're more fertile 14 days BEFORE you next cycle starts. You have to ovulate in order to become pregnant, and women rarely ovulate on their period.
It is possible, the pill is only 99% effective. You are also more fertile on your period. Wait two weeks and take a test?
