birth control
"At first, I didn't have any problems with this. No nausea, no weight gain, there wasn't really a change in the amount of acne I had. I was told it would help reduce cramps and amount of blood during my period, but it actually did the exact opposite. Cramps were horrible, my stomach was quite swollen, and the length of my period was increased and the blood flow was horribly heavy. I was told it could happen on occasion, but it was rare, so it's a bit unfortunate I had that reaction to it. At least it prevented pregnancy."
