Over the past few days I've had these weird pains in my pelvis that I can only describe as I feel like I'm in labor! They last for about 30-40 minutes at a time, and I've only had them once each day since Saturday. For about three minutes I'll have this really sharp, intense contraction, then it suddenly goes away. A few minutes later, its back. I'm on cd 7 and done with AF so it isn't menstrual cramps. It's much more intense than cramps usually are. It's sort of like when I miscarried, but that was in my back and now it's in the front. Anyone else ever have something like this? It has me a little concerned.
