I've always had long cycles, in the mid to upper 30 days. I've been testing for ovulation using OPKs. It's usually pretty accurate - AF comes about 2 weeks after I get the LH surge. This month, something went wrong with my OPKs. My son destroyed one before I could see it. Then the next day, I got a high (but not a peak). I usually have a couple of days of high before a peak. Not after this one, it went back to negatives.

Glow decided that my single high was when I ovulated. I'm now 5 days post when glow predicted my period would come (cycle day 37), and nothing. No AF, my cervix seems high, and I'm having creamy/sticky cm. I've taken HPT after HPT and they're all negative.

I'm so confused. I'm using the wondfo pregnancy tests, and they've never failed me before. think they can be malfunctioning? should I go out and get a different brand? or is AF probably going to show up any minute?
