33 weeks pregnant. Somethings wrong!

Lindsey.

For the last 24 hours I’ve just felt off like something is wrong. I’ve had extreme back pain, cramps, breathlessness, lots of pressure where it hurts to sit down to pee or even stand up. I feel dehydrated but no amount of water is helping. Can’t get comfortable or sleep. I keep feeling like I have to poop but when I try it’s just a little and runny.. sorry tmi..

This is my first pregnancy and the doctor told me I’m measuring 2 weeks ahead. Should I go to the hospital? Any input will be helpful!!

Thanks in advance!
