birth control
"My GYN prescribed it. She said I could have unprotected sex seven days later. The first day I took it, I felt nauseous but I expected it because I did my research. I had unprotected sex on the eighth day- 4 days before my expected period. My period then was late. I thought I was pregnant but the tests results were negative. 
I then had a horrible migraine lasting for more than one week- on and off during the day. I never get migraines. My cramps were horrible and I felt like I was dying. I had really bad neck aches, back aches and leg aches. 
I was supposed to try it for 3 months then report to my GYN but I couldn't do it. "
