Im 29weeks and 1day and having contractions

Christy • I'm a Homemaker!! I have my little boy that's 1 years old and I am expecting baby #2 in Sept 29 2016!!! It's a Girl!!!

How soon can someone have braxton hicks?? Ive been having them off and on all day.. i know it to early to be labor contraction or pre term labor.

Should i call my doctor?
