This is the first month of TTC since my tubal reversal. Yesterday I was working out like I do religiously, just legs nothing to hard and I started to get unbelievable cramps. I could still workout but lowered my weights and reps to ease the cramping. I'm cd 20, not exactly sure when I Od because I didn't use opk and my cm wasn't tracking what glow was predicting. I was on clomid 5-9 and i took the pill the night before so I had less side effects. I've been having early pg signs but idk why the cramping would happen so early. Has anyone else ever had anything like this happen before ?
