Unable to pee

Megan

I am 15 weeks pregnant and for about the last week or so when I get up in the morning I can not pee. No matter how hard I try. Sometimes walking around helps and then I’m able to go and sometimes I go 1-2 hours without being able to. When I finally do it’s a lot. I don’t think it’s UTI since it only happens in the morning. Anyone else ever experience this? I go to dr this afternoon
