I'm a sixteen year old female and have been taking birth control pills for a little over a month now. I'm very regular with taking them and have never missed a day and take them about the same time every day. My brand contains in the last week of a month pack, two pills of lower dosage of hormones and two placebo pills. Last week, my boyfriend and I had sex and used condom, but this was on a day that was a placebo pill. The condom didn't break and he didn't ejaculate inside of me. Lately though, I have been experiencing slight cramps and very light spotting. I am nowhere near my next period. Is it possible that I could be pregnant?
