Braxton Hicks

I’m getting a ton of Braxton Hicks. nothing helps. Not getting off my feet, water doesn’t help literally nothing. (I’ve been given fluids at Er) and they still were there. They are increasing. Still not progressing into labor (i don’t think) but i get them all day long. Not consistent but how many I get is nuts. I think baby might come earlier than expected. I’m 36 weeks. I started having lower back pain occasionally and random cramps occasionally as well. I was told I’m having contractions close together at the ER and they were big but I was not feeling them whatsoever. So they sent me home because my cervix wasn’t dilating either. But the BH are ridiculous. Do they get even more frequent the closer you near birth?
