emergency contraception
"I am 24 years old. I was on the birth control pill microgynon for about 5 years straight. I got off it in the beginning of March. On March 26th, right before my period week, we slipped up. So we grabbed plan b. I had taken it before I was on birth control, and had no side effects. But this time I felt everything. So for two days I felt nothing. And then on the 2nd day I got shaky & hungry.  On the 7th day I cramped, sore boobs, emotional, & hungry until 20 days after I took it. I got my period exactly a week late. I cried so much during that time. But trust me. Your period will show up. You absolutely will feel pregnant but chances are, you aren't."
