Is it possible you could be a little dehydrated? I think dehydration can sometimes cause abdominal cramps. I usually feel less crampy if I drink a big glass of water.
Have them check for cysts via u/s when you go in for your appt. I had the same pains but no cramping and they found a cyst on my ovary with the u/s.
I have had some pains also alot of times I find its gas....lol.....but when I sit down for a long time or squat and stand up I have this pain that feels like somthing is ripping, Im told thats normal, also when I go up and down the stairs at work I get this great amount of pressure in my abdomen and pain, Im not sure what that is.....Ive never had a child before so Im just marking it up to being pregnant....
