Which can it be?

I'm 40 weeks 2 days and I had sex with my husband like an hour or so ago I cleaned up after and just recently I had clear fluid in my underwear. Didnt necessarily smell like cum or pee. But still wondering.. do you think it could be cum still or maybe my water broke and leaked out.

Also; I have been having on and off cramping/ tightening lately too if that helps. And now am starting to feel a little bit of cramping/tightness after it happened. Already more than halfway thinned out
