About 3 weeks ago I missed my doc appointment for my DepoProvera shot, and not even the day after I started my period. Since then I've had it. Its heavy most of the time, one day I won't have it. The next day I will. I've been going for depo shots for 3 years now and had my period maybe 3 or 4 time throught 3 years. Is this typical for someone who has been on it for so long? How long is this going to last? I'm sick of it >;)
