I've been on the depo for 2 years. My Ex bf and I had unprotected sex frequently. I've been very responsible about keeping up with the shot, but they have suggested I take calcium supplements to help with what the depo destroys. (I haven't taken them) Now with my bf we are having unprotected sex every night. I've never had regular periods and i've spotted unpredictably and I always bleed during sex. I have not had any nausea but my boobs are growing and maybe my tummy? What are my chances that I am pregnant ??? ( getting tested on my next shot anyway )
