abnormal uterine bleeding
"Worst decision ever!! Got depo shot after 6wks postpartum thinking it was the most convenient birth control method. Oh, so wrong. Got it 4-17-15, started bleeding 5-1-15, a month after I am still bleeding.  Limited sex due to period bleeding, it's not pretty. Terrible mood swings. Increased cravings for sweets and junk food, dizziness, very tired and sleepy. Well its a horror story. I am not going back for a 2nd shot, no way. I will never get another shot of this medicine that transformed me in to a non stop bleeding witch."
