I recently switched from depo back to the pill. I was on depo for only 3 months but I was bleeding it spotting for 2 of this months. I started the pill again when I had 2  weeks left of depo (doctor suggested) and hafway through that pack I got a full blown period. I didn't take the week break between packs and am now on my second week in my second pack, but have heavy bleeding. Is there any way to stop it? How long does this typically last?
