Could be. Watch them....if you drink a cold big glass of water and lay on your side, do they go away? If so it's braxton hicks. Dry drinking water anyway due to dehydration is one of the main causes of Co Tra tons to start. If you still have more than 6 in an hour, go in and have them check you out.
They have been irregular today but I have a doctor's appointment tomorrow so ill talk to them then. Tomorrow I'll be 37 weeks so I'm not to worried
Let us know how it goes tomorrow!
