My boyfriend and I are in a long distance relationship and I went to visit him in December. I am on birth control and I take it consistently and we used condoms as well. When I got back home at the end of December I bled for a few days (I was taking my placebo pills at that time). Now it's the end of January and I haven't had my period yet. A few months ago (when I wasn't having sex) I skipped a period as well. Could I be pregnant?
