Pee or fluid?

20 and 2 days today. I pee a lot and this is my third so even before pregnancy I peed a lot and had trouble making it to the bathroom sometimes. And it doesn’t happen a TON but enough for me to notice when I bend over a little liquid comes right on out. I’m pretty big already belly wise so my guess is it’s just a little pee leaking from time to time but I haven’t had this happen with my two previous pregnancies. Anatomy scan Friday the 8th so we’ll see my fluid level. But just wondering if anyone else has this happen or any advice. Thanks!
