Depo Shot

So I've had the shot for almost 2wks (Ik not awhile) and I'm wondering if any of you guys are having the same problems as me. My sex drive is almost nonexistent..(which isn't me) and I've just been pissy at everything..even my bf and he isn't doing anything wrong. Have any of you switched from the depo to the implant? Because I'm seriously thinking about it once my 3mo is done. Thanks!
