I keep thinking I’m leaking amniotic fluid 😩

22 weeks pregnant. How do I know for sure it’s not? It comes out in small gushes a few times a day and there’s little white specs in it...but it’s just a few drops definitely not enough for a panty liner or pad. Just enough to wet my finger or a few drops on my underwear. Is this just pregnancy discharge?! I don’t want to be dramatic and go get checked. This has been happening for weeks now
