Discharge?

Holly • 21/ loving being a mommy💙😘 / engaged to my best friend! 💍💗
So I went to the bathroom when i woke up today. But before I actually went to the bathroom I wanted to check my cm. When I did I couldn't tell if it was watery CM or if I was just wet from being turned on when I woke up (sorry tmi)! How can I tell the difference?? Yesterday my CM was more of creamy and sticky. Can it change overnight? TTC and have been watching for EWCM...
