birth control
"I've been on the shot for 2 years, I've experienced no weight gain or any of the other common side affects. I have not had a single period and only spotted one time. I started the shot when I was 16, and now that I am 18, I want to change methods because it is recommended to not be on the shot for over 2 years because it can lead to osteoporosis. I have tried other methods before, such as the patch and the ring. But the shot was my favorite of them all. If I didn't have to switch methods, I would definitely stay on the shot."
