I had a baby in january and right after i got my depo shot, ive never been on any other form of birth control. but since then ive been bleeding non stop. itll stop for a few days then start up again. Its a brownish color and smells really strongly of like, pennys.... Is this something i should be concerned about or will it eventually go away? I asked the midwifes about it and they gave me antibiotics and it stopped for maybe a month and now its starting again. I got my last shot a week or two ago.
