emergency contraception
"I've taken Plan B on three different occasions. The first it was more of a precaution. The second and third times I took the pill were only a month apart. Both were a couple days before I was supposed to ovulate. I took Plan B within a couple of hours each time. I experienced moderate cramps each day, accompanied by tender breasts and headaches with both. I started my period 3 days before my cycle was due to start the first month and 4 days before the second. I was worried it wouldn't work 2 months in a row, but it did. The side effects and the cost are definitely worth it. 

No worries! I'm a 100% believer in Plan B for emergencies!"
