I got the depo shot of July 2011 I've been off it and never got it again after that between the times of being on no birth control I was bleeding for two to three months finally went to the doc in December and got on sintec now the bleeding stopped I finished the pills and have no way of getting more birth control pills & now im on my period it's heavy now but does this mean I will keep bleeding again? Because I'm already anemic and can't go through the random passing out again.
