Diarrhea and nausea

As

Okay so I'm 35 + 2 weeks and I can't leave the bathroom for very long. TMI it's very watery and I have been having period cramps for a week. I have never had this with my other two pregnancies and a little worried. She's still moving and those are my only symptoms other than pulling muscles when I get up or down.

Is anyone else experiencing this?
