lots of Braxton hick contractions

I have been having Braxton hick contractions since 26 weeks they have gotten stronger and stronger, I am now 31 weeks and they're so uncomfortable. Could this mean I could go into labor earlier than my due date? I feel as if I'm about two weeks off from what the doctors say my due date is anyways. I just feel so uncomfortable lately. Has anyone experience this before? This is my 2nd baby and my first was nothing like this.
