Back to back Braxton Hicks?

Austin

I’m 27+1 with Di/Di twins, yesterday i went to labor and delivery I got the horrible cervical exam and I wasn’t dilated and my cervix is closed. I did a urine sample to see if i was dehydrated or if I had a UTI and I was cleared for both! I drinks tons of water, I’m not understanding why i keep having Braxton’s Hicks and they don’t hurt their just uncomfortable especially when I’m standing up or walking it’s so much tightest in my stomach it feel like it makes my stomach heavier.
