I have a question, but let me give you a bit of information.. I had my last period a few days before New Years and I should have had it sometime this past week. I had been feeling light cramping but period did not come. Yesterday, I had unprotected sex and he ejaculated in me about 3 times. We used spermicide foam the first time but he pulled out . After that, is when he ejaculated in me. About an hour later I took the Plan B pill. My question is, is it possible that I had already ovulated and the plan b pill not work? I did not get my period today either. (They are pretty consistent)
