early ovulation

Danielle 🐈 • Married TTC #1

I have a 28 day cycle.

I had EWCM from Saturday the 12th till yesterday (Wednesday) the 16th.

according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> my fertile window was the 13th to the 18th.. but today is the 17th and I have Creamy CM.

so did I ovulate sooner then what the app estimated?

anyone else O on CD 10 or CD 11?
