Help! Am I ovulating?

Stephanie • Autoimmune + Pregnant w/ our 1st angel👼🏻🙏🏼Children are a gift from the Lord -Psalm 127:3

I just signed up for this app and this is our first time TTC. I’m CD 17 today and had EWCM the 8th & a little bit the 9th and now today it’s back. But this app says I’m ovulating today? Im so confused. I thought EWCM came 1-2 days before ovulation? How am I ovulating today? I thought I ovulated over the weekend since that was 1-2 days after my EWCM. Any help is appreciated!! (I also have periods posted in the app as far back as December 28th hoping it would help with accuracy.)
