... unprotected sex before then and on may 12th. My doctor won't be back till Monday and that's when I have to wait, but is there any possibility I could be pregnant? I've been on the shot for about 5 years now so its always been in my system. I'm just freaked bc I'm not ready. Am I just loosing my mind or do I really need to be worried? Please help! (I'm 22 btw)
