First OPK - please Help Understand the dates

Dina

Hi Ladies! I really need your kind help in understanding when I should start using the clear blue advanced digital I bought yesterday!

According to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> picture attached I should be ovulating October 17th.

I am currently on my period day 2 which actually came 3 days early!

Decided to use the clear blue opk as we have not had luck with just using apps to monitor ovulation days.

This is my first opk test! Any and all advice and tips are greatly appreciated ladies! Thank you!
