I was on the Depo shot for a little over a year. I was put on it to try and stop abnormal bleeding. I have recently read on many sites that you should not even take depo if you have unknown bleeding. anyways, i always had abnormal periods and when i was on the shot i didnt get my period at all. I stopped taking the shot in january and i got my period right away and it was actually getting my period once a month from then on but now 8 months later i am now a month and a half late (so my last period was 2 1/2 months ago. Im not sure if something is wrong. my periods before the shot were always late and abnormal but not this late....is this common 8 months after taking depo? I did take two at home preg tests and they were negitive. i also have been having some nausea.
