Advice would be lovely 😊

Hey ladies I have pcos. I have regular periods and have for a long time. I’m not on any contraception haven’t been for a year. I wanted to know if it is possible to ovulate but not get a positive opk I ask because I get ewcm every month with out fail I’ve also had my bloods checked to make sure I am ovulating and they were perfect.

I do opk tests but they never seem to be the same colour/ darkness so I’m confused as to why this may be ?

The are dark but not as dark as each other.

Any thoughts or advice would be greatly appreciated baby dust to all ❤️
