Tightening at 27 weeks

Hey everyone, I’m 27+5 and have had Braxton Hicks lately.. and yesterday and today I have constant tightening for several hours. I called the nurse yesterday and I have my next appointment Monday so I’ll ask the doc too, but I wanted to know if anyone has had a similar experience.

Nurse said that it’s likely dehydration which is what I was thinking too.. we’re in Colorado so it’s dry and I haven’t been able to drink a lot due to nausea but past couple weeks I’ve made it back up to my regular 40oz. But the nurse said I need to be drinking 80! So I’m working on that but it still is happening and it’s worrying me.

This is actually my 6th baby, but I’ve never experienced this so early on!

Any stories or thoughts? Thanks!
