So my boyfriend and I had unprotected sex, and we are sure he did not come inside me. A week or two later, our condom broke. So I took Plan B. A couple days after taking Plan B I started my period around the time I usually have it. Now, presently I feel lower stomach cramps and it might be in my head but I feel much more bloated and bigger at my lower stomach area. Is it possible I might be still pregnant after taking plan B? From the condom breaking, or the unprotected sex?
