birth control
"I'm 18 going to be 19 soon. I had really heavy periods for 8 days straight and my period would come a week early. It was regular just less than a month until each one and I also had really bad cramps to the point where I couldn't move. The pill was my first option and it made me bleed for 3 months straight. A while later I was considering birth control and I finally chose the Depo-Provera, it was the perfect choice for me. Once I got the shot I never got a period/any bleeding again. I personally didn't gain any weight. All the side effects didn't bother me. And works well against pregnancy. I've saw a lot of bad reviews but mine was perfect so everyone's body is different. I would recommend talking to your doctor. He/she will know what's best."
