I'm on the depo shot and I have been for almost a year now and I get my period every three months or so but I get it for at least a month or longer , anyone know why? It's making me crazy I've gone through so many tampons & it goes away and I think I'm done and then I pee and it comes out. I don't know if I should just get off of it or not but it's been so effective for me I don't want to
