Braxton Hicks

So I’ve been having Braxton Hicks off and on since about week 16. And in the past day or so, I’ve noticed that they have changed. They used to be up high and a lot of pressure. But now they are lower and more painful, like the contractions I had when I was In Labor with my daughter. I’m 32+3, and they aren’t consistent or anything. Has anyone else noticed a change in BH?
