birth control
"I've been on the shot for about 9 years on and off. What I mean by on and off is that I take about 3 shots instead of 4 shots a year. I started doing this because after the 1st year of being on the shot I found out I had precancerous cells in my cervix. Not positive that the shot caused this but I give my body a break for several months before I start again. Every time I start the cycle again I get a different side-effects. I usually have a very high sex drive during the 1st month and 1/2, I always have acne, always have mood swings and depression, sometimes I get headaches, and I gain weight continuously regardless of diet and exercise."
