Hi there. I have started taking contraception within the last 6/7 months. For two months I was taking Cerazette which implemented a massive weight gain so I switched to Depo Provera which I have had injected twice, and during the first 12 weeks I noticed complications with menstruation. I am now on my second injection of Depo Provera and although the nurse said my cycle should regulate, my bleeding is becoming thicker and darker with many clots. Is this normal?
