Hi there and welcome. Agree with above, important to take them in a regular fashion. Read the package instructions to be sure you are using it correctly. Also, look at the package directions to make sure you have been taking it long enough to be active. I like girls to wait one month to be safe but the package insert may say two weeks. Definitely check this.
But once it is onboard, then you are safe from pregnancy with a low failure rate of getting pregnant on the pill (most often because the pill was taken incorrectly). You are NOT protected from std's though.
good luck hon
It depends. When taking birth control pills you have to take them regularly. That means the same time every day in order for them to be fully effective. If you haven't (because you're like me and forget or something) then it is probably not safe to have unprotected sex without running a risk of becoming pregnant. My best advice, have him pull out or wrap it up.
Hope this helps!
