birth control
"I started the birth control last summer in August and stopped it this April. For the first 6 months of taking the pill I had no problems at all, I felt normal except I did get acne which went away after about 1-3 months. It shortened my period to about 4-5 days instead of my normal week long and a half periods.   But after 6 months of taking the pill I would sometimes get my period early by about 8 days and then the next month it would be back to normal. Also I would get bad cramps and back aches which appeared after 6 months. This was bothersome to me, especially after the pill working great for about 6 months. The early periods, cramps, and backaches were doable but i decided to switch off it to loestrin 1.5/30."
