Did I miss I my ovulation????

Sh
Since the last day of my period I've been testing with opk's everyday and have gotten negatives. But last fri thru sun I was super busy and wasn't able/forgot to test.
I remember on Saturday my (tmi) discharge being super watery. Also I track on two different apps and there giving me two different dates. 
Is it possible I missed it last weekend or it maybe on the horizon? My periods run between 35-40 days. Thanks for the help!
