Watery Discharge

I am 18 weeks and for the last few weeks have had extremely watery discharge. It’s not constant but leaves pretty large wet spots on my underwear several times a day. I went in around 14 weeks because I was nervous about it and the doctor said everything looked fine. She did not test for amniotic fluid though. It does not have a sweet smell. Sometimes I do feel like it smells like urine but other times I can’t tell.

Just wondering if anyone else experiences excess watery discharge? Usually picks up through the day as I hydrate myself more.
