emergency contraception
"Took plan b back in December after unprotected sex and got my period a week later, which was also around the time I should've normally gotten it. It was kind of heavy and lasted 5 days, which is normal for me. Well I had unprotected sex again in January and had what I think was a period 2 weeks after. It was just really light in flow and was more brown than red and it lasted 8 days. Now I'm waiting on my next period which is now 21 days late. I'm cramping, bloated, nauseated and even have thrown up once and had diarrhea. I've taken 2 tests and both came out negative so I have no choice but to continue playing this waiting game I guess. Needless to say, plan b works but its side effects are HORRIBLE."
