How to tell when ovulating?!

Zoey

I'm really struggling to figure out when I ovulate so I was just wondering if any of you lovely ladies out there have any tips of small things that usually give you a sign that you're ovulating or about to? I try to track my cervical Mucus (the raw egg white discharge) but doesn't seem to consistent 😣I've been using OPK tests for the last few months and it keeps coming up no LH surge 😣 and I can't really afford to buy a kit for every day of the month unfortunately 😭
