Ovulation ..

Chloe

So about from 7/15 to yesterday 7/18 my CM was egg whites. Especially yesterday. Today my CM is more creamy and my Cervical position feels like it's more firm. But I'm not supposed to ovulate until tomorrow 7/20. So I'm wondering, do you think I ovulated yesterday? Or does your CM change the day of ovulation? My CM definitely isn't egg whites right now.
