Watery substance ???

Now yesterday I had a watery substance leaking out of me down there. Not urin. Still no period and 22 days past ovulation. I've read a few blogs where sometimes woman that are pregnant their cervical mucus turns to the watery mucus. I've been having inconclusive tests where they are positive but the control window doesn't work. I plan to test again next week. Seems like every day Nausea gets worse. Can anyone clarify this for me please.
