Has anyone ever experienced this?

Zaria

I'm 18 weeks and this is my first pregnancy. I started having sharp pains in my urethra when I sit down sometimes. I've been having this pain since 16 weeks and 4 days. Its so uncomfortable and annoying. I've been tested for a uti and its come back negative. Is this normal? I tried talking to my doctor about it but they said as long as its not a uti you should be fine. They said if the pain gets worse go to labor and delivery. Has anyone had this?
