I missed a pill on Thursday and again on Friday. However, I took 2 Saturday morning to make up for it. Saturday I had unprotected sex (he pulled out, but I know that's not perfect). I continued to take 2 pills Sunday and have been taking it everyday now. On Tuesday (3 days later) I took a plan B pill. It's not time for my period yet. The only thing I've been feeling is slightly constipated (but that could also be because of my bad eating habits lately) and after I took plan B my breasts have been sore. Is it likely that I am pregnant?
