While laying in bed this morning, after I woke up to pee at 5 AM, I had strong cramps and lower back pain for 2 hours. I managed to doze off a little more so it wasn't so bad that I couldn't sleep, but I was starting to get a little concerned and thought about calling my OB on his cel when it got to be more of a decent hour. I got up at 7 AM and it went away mostly. Hmmm. Anyone else have that? Nothing else out of the ordinary has happened.
