Help 😩

I’m currently 31 weeks pregnant. Today I’ve been having on and off period like cramps. When I was helping move boxes that weren’t full I had to squat down to pick something up I noticed that some watery discharge came out. Then I went pee and while I was peeing it sent a pain up my stomach the on call nurse said she doesn’t know what to tell me. I just need to know if anyone else has had this before and or if I should go in 😩
