Wondering if I'm out this cycle?

So glow estimated my fertile window to be from 12/2-12/6 with my peak day being 12/4(33%). I had begun ovulation testing 11/29 but had yet to get a positive...on 12/3 the test was positive but only slight but not dark enough to be considered a positive so I kept testing but the line never got darker..I still kept logging my data and noticed glow changed my window to 12/1-12/7 which I thought was weird. On 12/5 I noticed I had ewcm in the morning but was unable to bd so I hoped to do it when I got off work and when I checked cm again I noticed it was no longer ewcm...does that mean I ovulated 12/5? Glow says today 12/6 there is a 33% chance and tomorrow is my ovulation...I never got a positive on the opk so I don't know if I should keep testing or just bd to cover my bases just in case? Also if anyone could explain what the percent means on glow. Today I have a 33% chance of becoming pregnant does that mean today i ovulate today? Any insight would be greatly appreciated 😃
