OPKs and PCOS- very late positive!

first post, and first month using glow!

I have pcos but cycle has been regular at 28-30 days for around a year now. TTC 4 months for #2.

This month I got almost positive OPKS CD 22/23 and EWCM, then a few days later more EWCM but negative OPKS. Yesterday (CD 31) more EWCM and a positive OPK but af was due today.

No sign of af but more EWCM today. I’ll be doing an OPK this afternoon and BD last night just in case!

What do you think is more likely?

Ovulated late/twice

Long cycle

Annovulation

False positive OPK?
