Braxton hicks

I'm 37 weeks and 1st time mom. How many braxton hicks is normal? I've been on bed rest since 23 weeks because of my cervix shortening prematurely. Thankfully I'm 37 weeks and still pregnant. Doctor at my 36 week check up said I could go any day since I had stopped my progesterone and there was nothing left of my cervix basically. All last night I noticed my stomach kept tightening up. It didn't hurt. Just uncomfortable. I would just drink water and change positions. I do have pain and pressure down there. Baby has been head down the whole time.
