Taking more birth control than you're suppose to will make you sick because you're bombing ypur system with way more horomones than you're usee to I suggest stop taking them, wait until you're next period and start on the first day of it. After you start taking them it takes one month for you to be safe. In the meantime use condoms or abstinance. I highly doubt you are pregnant. Just don't stress and freak yourself out over this.
Though you can get pregnant from precum I think since it was the last day of your period, you were not ovulating yet. I think since you're on bcp & using condoms, its unlikely you're pregnant.
I've heard that the morning after pill is like 'the pill' in a much higher dose, so its possible that the 2pills you took could work
I agree with the previous poster. taking the pill doesn't work like that.
If it was the last day of period you more then likely were not ovulating so you can't get pregnant without ovulation. So really just make sure you are careful, just follow the directions of the birth control you were given as well as making sure you are also using condoms.
When you take more birth control than whats prescribed usually one a day. It will make you sick. And I honestly dont think you takin those pills will pervent it.
