When was ovulation?

Bridget

Last month I had a failed IUI and instead of a 28 day cycle I had a 31 day cycle bc of meds. I wasn’t going to track this month but I randomly decided to track on Wednesday and I then decided to let my app read my sticks Thursday on CD 16. Am I about to ovulate or did I already ovulate? I’m not sure bc I started tracking late. I’m thinking having a 31 day cycle also results in me having a later ovulation.
