Fertile window supposed to be this week, but all negative OPKs

Taylor

Glow has pretty accurately predicted my periods and fertile week/ovulation in the past (last months OPKs synced up almost perfectly with when I was fertile and ovulating).

My period this month was almost a week late (and I’m usually pretty regular). Thought I may have been pregnant since I was spotting all week and finally started getting a normal period flow on Friday night when my period was supposed to start on a Monday.

Glow predicted my fertile window to start on Monday. I’ve taken the clear blue digital tests all week, and today even I’ve gotten a negative. Am I just ovulating late? I’m worried I’m not going to ovulate at all this month now, just looking to see if this has happened to anyone else.
