So I got the depo shot in June and was due for the next one in September but I decided not to do it. I had my period at the beginning of August but haven't had it this month. Is this normal if you have only gotten one shot? I've already taken 3 pregnancy test and they were all negative. I took them because I thought one night I could've gotten pregnant because me and my husband haven't been using anything else but pulling out. If this is common with the depo I won't worry about it but I think if I don't get my period this next month I'll go to the dr. What do you all think?
