Thanks ladies for responding
It could be Braxton-Hicks, or contractions if it's on and off cramping that's Braxton-Hicks, but if the pain increase and are constant contractions.
Can be Braxton hicks or also growing uterus.
Most likely your experiencing Braxton hicks contractions. When they get stronger and last longer then it is active labor.
I'm 34 weeks and cramp off and on for about three weeks. I'm curious too.
