Hmm... I'd wait & see if there's more. I've had watery discharge that wasn't fluid. Kinda similar. The discharge towards the end of all my pregnancies was different. Not one was the same!

My waters with DD1 was a slight leak every 20 - 30 minutes. Enough to leave a patch on the bed the first time, but not enough to fill a pad more than every couple hours after that.

DS's was different, but still only a leak. Just way more each time

Maybe do something to help bring it on, like a DTD or a walk, then have a sleep & see what happens. Only one of my labours started when I was awake.

(Little bit excited to see you're that close!!)
