I have been on birth control for 4 months and for the first time this month me and my boyfriend had sex without a condom. In fact it happened 3 times. He always pulled out and never did anything inside me. My period is due in 4 days and I have never had pre period breast pains before. I am worried that I might be pregnant? The pain is only In one breast and it is not all over, just under my right arm at the side of my breast. It is sore to touch but is in quite a small area. Thanks :) by the way, I take my birth control at the same time every day and haven't missed a day since my first month

IT could be a slow reaction to your birthcontrol, since they contain hormones that will convince your body that it is already pregnant and doesn't need to ovulate. Side effects are your body thinking it is pregnant. Bigger boobs and weight gain are common.

I think this is coincidental. I think the pain, which is odd it is only in one boob and off to the side, is probably something other then the birthcontrol. I think it should be something to be checked out.

Chances are low that you're pregnant. You'll have to wait until you miss a period before you know anything. By missed I mean two weeks missed.Good luck!
