Hi, I have been on the depo shot for about 6 months now and I have been on it multiple times, even up to a year. I have never bleed while on the shot ever. It usually takes me about 4 months to start getting my periods again. My depo shot is supposed to be due late March but lately after drinking I have a light pink spotting, but besides that, it has been old blood for a week now. I have had severe abdominal pain after eating, as well as nausea. I took a pregnancy test and it came out negative. My boyfriend and I do not use protection as we are not worried about having kids, actually hopeful. I was just curious what this means. Like I said, it isn't normal for me to bleed on the depo. Should I go see a doctor?
