CD 24 No Ovulation

Brittney • Graphic designer turned CNA trying for baby #1.

I’m tracking my ovulation with an OPK and I’ve done so a few times before. Every time I’ve gotten an LH surge by now but not this time and it’s CD 24. According to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow App</a> I should’ve ovulated four or so days ago. Does anyone else ovulate later in their cycle sometimes or am I just not going to ovulate this month...?
