Braxton Hicks 37 weeks

Ash

I use to have Braxton Hicks starting at 27-28 weeks they would last at least an hour and be super painful..

Now I’m 37 weeks and they are totally tolerable and only last for 2-3 contractions??

I’m wondering why they have gotten shorter and easier to tolerate you would think they would get stronger or hurt just as much as they did before?

Any advice??
