I was on my period and my boyfriend and I had unprotected sex on Saturday and Sunday. I was supposed to start my new pack of pills on Sunday and forgot them out of town and I wasn't able to take a pill until Tuesday. I am a week away from having my period but I have had some symptoms that are making me nervous, could it just be my period coming or a chance of pregnancy?

Pregnancy is always a possibility, even if you're using birth control and using it correctly. You missed a few pills, so there is a greater risk, but, I'd venture to say that the symptoms you're feeling are more than likely because of the missed pills. You're putting a lot of stress on your body skipping pills, then taking them, then missing, etc. Your body doesn't know whether it's coming or going, so it is likely that your symptoms are because of that, especially if the last time you had sex was before the missed pills, and you were on your period during the last sexual encounter.

That doesn't mean that there's not a chance of pregnancy. There is. You'll have to wait until your next period is due. If you're late, try a home pregnancy test.

If you're not pregnant and want to lower the odds, use your birth control pills correctly, and use a condom as well. It's still not safe sex (there's no such thing), but it is safer sex.

Good luck.
