I took Plan B one day after the condom slipped off and no ejaculation occurred. My doctor told me to wait 5 days to start my birth control regimen, and to have no sex during those 5 days, even if it was protected sex. On the 5th day, we had protected sex. The next day, I started my birth control, and have taken it faithfully. I am in my last week of it, and yesterday, my period started, but something like skin came out of me. Today, my period is practically over. I feel like I had a miscarriage. Did I?
