ovulation after IUD removal

Mollie
I got my Mirena removed on 11/29. What I'm assuming was my period started on 12/1. Both Glow and Ovia are predicting my ovulation day to be this Thursday. I took an opk test today and it was clearly negative. I'm also not really having a lot of symptoms of upcoming ovulation, including the lack of CM. Is it common or normal to have this issue after IUD removal?
