If you aren't experiencing any pain or discomfort than my guess would be BH. Have they been getting closer together or all over the place time wise (time between, and duration of)? If it's just BH, they will sometimes subside by drinking a glass of water.
I agree with browneyedmama. I have braxton hicks frequently but there is no regular pattern. Are you drinking lots of water?
hmmm.... i would think they would be BH... have you tried timing them? are they consistent?? if they are consistant, i would suggest going to get checked out. let me know how it goes!! good luck
