OPKs after birth control?

I’m newly starting out in the TTC category and came off birth control about a month ago. I’ve been irregular since I can remember and started using OPKs to see if I do ovulate or if I don’t. Do I even start tracking now or is it better to save the stress for later?

As of right now, it shows I started having high fertility on the Clearblue tests on day 19 and it’s day 23 now with the same high fertility. I’m anxious to see if I will have that solid smile (peak fertility) instead of the blinking one (high fertility).
