emergency contraception
"Condom came off. Took Plan B about 48hrs later. Was super stressed. About a day before I was supposed to get my period, started having cramps, dizziness and  breast tenderness. Long story short my period was a day late but I got it none the less. It's terrible when you're so stressed out and thinking you're pregnant. The pill does work. My cramps are terrible though. I felt the side effects 6-7 days after taking the pill as well."
