Braxton Hicks

Kat • I am a Texan abroad with my sweet hubby and a beautiful 19 month old daughter and trying to conceive our second child.
Is anyone having Braxton Hicks contractions? What do they feel like? I think that is what I am feeling, tightening of my belly for about 10-30 seconds, then gone. (I am almost 31 wks.) Just want to confirm? Thanks!!
