So before I had sex for the first time last weekend, my period was already late about a week. Last time I got my period was February 11. I took plan b on the march 20th, 30 hours after unprotected sex, however i don't know when to expect my period. Today, now a week since I took plan b, I started spotting and being a little bloated with some cramps. Could I be pregnant? Or is this the pill? When should I expect my period? My cycles are usually 28 days. Confused and scared:(
