So about two weeks ago my boyfriend and I had unprotected sex for maybe 2 minutes, we then decided to put a condom on and just continue (he wasn't anywhere close to finishing) I usually take my pill everyday at the same time, but the next day I took it 5 hours late. Now I'm 4 days past my expected period and have only very lightly spotted for the past three days(light red), but have very mild cramps. Could I be pregnant?
