I was on the depo shot for the last six months and I was supposed to get it again between the 16th and 28th of October but I decided not to because it was affecting my mood. My boyfriend and I had unprotected sex until the 28th and he ejaculated inside me every time but after that we've been using condoms.  The past couple days my nipples have been really sore and are darker on the tips. But I haven't had a period for the last three months because of the shot so I'm not sure when I'm supposed to be starting it again so I don't know if I'm late! What should I do? If I so take a pregnancy test is it to soon or what? I need help!
