I been using depo for about 2 years and I always had my period couple days before my next shot was due i considered that normal for me to get it every time before my next shot, it's been 5 weeks since my last shot but I didn't take it because I don't want to be on depo anymore,,, I had unprotected sex days before " my supposed to be shot" and didnt get my period,I haven't had it since and I noticed my breasts were sore especially my nipples and I had brown discharges for a day a week after I had sex nothing else, can I be pregnant?
