TMI!! Diarrhea at 33 weeks pregnant??

Randomly out of no where I had to run to the bathroom...it was super watery. Very loose stool. I haven’t changed my diet at all.

The only thing that’s changed in my pregnancy is I may have preeclampsia. Waiting on my results tomorrow.

I heard it can be a sign of preterm labor?

I’ve had back pain bad but I hear that can also be normal.

Also been super nauseous and having headaches. Trouble sleeping.
