OPK question

So im sorry for the silly question but this is my first time using OPK. I started testing on Sunday (cd11) since I had ewcm. Until today one line was always darker than the other which on the box says no OH surge detected. Today I tested this morning and the line was even lighter. I still have cm but its thin now (sorry for the tmi ). Does this mean I might have missed my ovulation period? The test said I had to have two dark lines to control ovulation. I hope you girls can give me some info since im new to using OPK. Thanks if you read all this.

Re: OPK question

For me personally I'd usually have EWCM roughly 2 days before O was confirmed with a smiley on the OPK.....even if the lines are coming up faint for you, I'd always go by the signs your body is giving out, so make sure to any time CM is going on.....but I'd continue testing anyway for the next few days to be sure......good luck!!!
