Too many Braxton hicks ??

I'm 27 weeks pregnant with #3 and I feel like I have Braxton hicks contractions ALL THE TIME every time I stand up I have one when im sleeping they wake me up , when im out shopping I have to stop in my tracks and take a minute . This has been happening for About a week or more and they actually hurt . With my last baby my water broke during what I thought was a Braxton hicks contraction on my due date . I cant tell if I'm having a really contraction or a fake one I feel confused
