I started the Depo shot in November 2011 and started having constant vaginal bleeding from spotting to heavy everyday (sometimes it was a gush of blood that soaked through everything). I stopped using it after January 2012 and the bleeding never stopped until I became pregnant that July.
My son was born at 32 weeks apparently because of an incompetent cervix.
I bled for three weeks after I gave birth then had somewhat regular periods until this month. I had my period and have been spotting and bleeding brown blood for three weeks since, sometimes with black blobs in it.
I've had pain with intercourse and a lot more hair loss than usual. I also weigh less than I did before getting pregnant without changing my diet or exercising (I'm 5'9" at 118lbs) and have tons of old and new bruises on my legs.
