Is this been happening to anyone else?

Okay so first off sorry for the tmi. I am 36 weeks as of yesterday. Starting yesterday I have had really watery diarrhea. I've been drinking tons of water so I can't be dehydrated. I also have had an increase of clear discharge today. Has anyone else been having this lately? My due date is January 20th but my doctor only wants me to go to 39 weeks since I have gestational diabetes and baby boy has been measuring big.
