I'm currently using Depo, I've been on Depo since June, 2011. When I first started using Depo I caught hell with all the different side affects. Any who .. my long term boyfriend and I recently had sex on November 3rd, yeah *TMI and two weeks after that I started having sharp pains in my right breast .. I thought nothing of it because I'm thinking "Ok, it's just a weird spasm," until a week after that I started noticing back and stomach pains then I started feeling nauseous but I wasn't throwing up. I started taking naps and no matter how tired I am that's something I don't do. I'm updated on all my shots but I don't feel like myself... What's wrong with me? >.<
