Opk’s

Hey guys, just started trying 2 months ago and am in my second cycle in. Using the Pregmate strips and clearblue advanced digital, got my high fertility on 11/16 but it hasn’t turned to peak. I’m a serial tester so I’ve been testing once in the morning (I know it’s a no no with opks but had a lot of strips so why not) one in the afternoon around 5 and sometimes later if I would get curious and not positive on the strips or clearblue digital. Getting discouraged since I’m on CD 16, had egg white cm 2 days ago so made sure to BD but only had it for a day and today just have a lot of discharge but not egg white. Line is darker some evenings but only about 50% or lighter others, getting a bit confused. Anyone have experience with not getting positive or peak? Thank you!
