Am I leaking fluid?

I’m almost 32 weeks. Fluid level was normal at last scan (29 weeks), but since the first trimester I can’t tell if I’m leaking fluid or urine? It’s clear, no scent really, and I can’t feel it happening. It’ll be so bad it’ll be enough to get onto my pants even. How do you tell?

I’ve been not saying anything since I was having biweekly cervical scans due to my son being premature last pregnancy, and the fluid levels seemed fine. Those ended 6 weeks ago though. I don’t have a scan for a few weeks.
