39 and 1...A lot of discharge?

So I’ve been having a lot of discharge this AM. I sat on my chair and soaked thru my panties, and sweats to the chair. 🤦‍♀️ I thought my water broke but it was a creamy white discharge. So weird, annoying and gross to me lol. I am wearing panty liners now obviously. Has anyone else had this?

I have my 39 week check today at 1:30 so I’ll bring it up to my dr.

Just wondering if any of you ladies had that before.
