First postpartum period

Victoria

Ok ladies I'm losing my mind I'm going on a month and a half of this period and it's starting to get me down. It started back around the first of Jan and I spotted super light for about 2 weeks then it kicked into high gear for about 10 days heavy I was losing clots the size of my hands. Now it has been going on fluctuating between normal flow and extra heavy with about golf ball size clots. Is this normal? I know the first period is the worst but omg! I'd like to use NFP and can not go back on the pill due to high blood pressure are there any other options to regulate this period. We also would like to start trying sooner then later so an IUD or shot isn't an option either. I'm also 10m postpartum and on 2000 mg of metformin a day and breast feeding
