How to get EGG white CM?

Abbs

I have PCOS and we are about to try for another baby and before I used CM as <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> because i never got a positive Ovulation test and CM was just easier. Well now I have like almost No egg white CM ever and it’s so har soft me to track ovulation. Anyways my question is how can I increase that so I can track it easier? Is that even possible?
