So confused did I already ovulate?

Araceli

So this cycle I was late on my period i was about a week late and on my Premom app and this app it’s telling my I’m not suppose ovulate til CD23, but it doesn’t seem right for me cause I ovulate this late I didn’t start testing til days ago and the first to times I got a high and now I’m getting low, I’m scared I missed my chance for this month already, help?!
