37 weeks! Braxton Hicks

Heather

I’ve been experiencing a lot of what I believe to be braxton hicks contractions, however the only difference being it’s not so much painful but feels like huge pressure in my head and lungs. It feels almost like blood rushing to my head. Does anyone else experience this and if so should I be worried? I’ve brought it up with the hospital but they said it’s normal so I figured yeah probably but I’m not entirely sure!
