birth control
"This shot is terrible and I do not recommend it at all. My mood swings are terrible, I was put on an anti depressant because it made my anxiety terrible, and the abnormal, random, heavy bleeding with no warning after being on it for almost a year SUCKED. Not only was the bleeding random and heavy, it was for weeks at a time too. The shortest period I had was about a week. The only good thing that came of it is it definitely prevented pregnancy for me and I didn't gain weight from it."
