ttc after baby but opk’s are all positive?

My baby turned 1 last month so we’re going to start up again next month. I wanted to start testing which days I’m fertile so I’ll have a plan for next month. However, I’ve been testing everyday 2x a day since cycle day 14-22 and they have all been extremely positive. Only tonight’s test showed negative. My period has been back the last 3 months pretty regularly and I used to ovulate around day 16.

What do you ladies think? Are my cycles still messed up after baby or did I ovulate around cycle day 16 and just stay positive on the opks till now ?

Thank you. 💜
