I was the same way. I remember crawling around on the floor because I couldn't stand up, the pain was so bad. I still get cramps, but it's nothing compared to how it was before the pill. I went on the pill early, and did not see it as a license for sex. Since your daughter is so level-headed, I'm sure she has morals and values and will see the pill as a treatment for her pain-so she can live her life again.
