OPK Help, possible tmi

Two weeks ago I had a test that looked like this, then the next day the test lines started being extremely faint. Two days after that my cervix was high and my CM was heavy and watery, so I assumed I ovulated but missed my surge.

Today I have lots of CM that's between EWCM and creamy/sticky, so I took this on a whim. My pregnancy test was negative this morning, AF due tomorrow (based on supposed O two weeks ago.) My cycle has been funky since stopping birth control in April.

Any advice is appreciated! My first month using OPKs, this is the Answers brand from Walmart.
