Extreme cramping 8 weeks postpartum

For the past 2 weeks I've been having extreme menstrual type cramping that feels as intense as the first few hours of labor, not pleasant! I'm breastfeeding and haven't had any cramping/pain since the second week postpartum. I feel like I'm about to start my period any second but nothing's happened, just more cramps. My doctor has told me to try midol and Motrin but neither helps much. Is anyone else experiencing anything like this? Any suggestions of how to cope? At this point I'd welcome my period just so I can have a real reason for why my body is hating me!
