CM changed after exercising...

Ashley
So around 3:30 I did a CM check when I took my OPK, which was negative, and my CM was slightly creamy, but more wet than yesterday. It's now 7:30 and I just got back from a 3 mile run and my CM is now egg white and stretchy. It's CD12 for me, Glow says I will ovulate CD16. Should I test again or wait until tomorrow? Is it typical for CM to change after exercise?
