confused opk

I'm confused... 2nd time this month that I have had a positive opk. On the 17th and today both with ewcm. Is it normal to have positives more than once? According to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I should be due AF today. Recently diagnosed with pcos x
