Hello, Doctor.
I have some questions regarding pregnancies and I am hoping you can help me.
My boyfriend and I had unprotected sex two days ago, and it lasted about three minutes. He did not ejaculate, however he said he was somewhat close to. I have taken Plan B a few weeks ago after another instance of intercourse (he did not ejaculate then, either), and I am not sure of the chances his pre-ejaculate (if he did this time), will get me pregnant. I bled a few days after I took the first Plan B pill. I am wondering if I should take another one if the chances of our last intercourse will get me pregnant. My period is very irregular and I have not received a full period ever since I took the first Plan B pill. I don't know if I should take another one, because I feel as if I do, my period will be irregular for even longer, but the chances of pregnancy will lessen. Please help!
