If you are on the pill and have taken them properly without missing one, then you should be ok, but birth control pills does not guarantee that you will not get pregnant, because there is always that percentage that it is possible, also, birth control pills do not protect you from STD's only a condom or abstenance. If you think you might be pregnant, purchase a pregnancy test or make an appointment with your gyne to be tested. Always practice safe sex and make sure he always use a condom. Good luck,Judy
Birth control does not protect you from stds. You need to maintain your sexual health by using condoms. You should also go through and get tested if you are sexually active.
As for your pregnancy you can get pregnant if you are on the pill. I am living proof of it. Granted its not common.
