birth control
"I got the implant August of 2015 right before college and I bled for at least 4 months straight on and off, but mostly on. It's now February 2017 and I have gained 30 pounds!!!  Yes I will say that it is effective but I would only recommend it if you don't plan to have sex. For a while, right after I had sex I would get my period and it would be super heavy which was nothing I ever experienced. I will say because of reading other reviews that their may actually be some truth about the depression thing. But I plan to get it out next month so that I can go back to my old size. But other than that no period, I just get them randomly."
