TTC after Mirena without AF

Hey guys not sure which category this goes in but here it goes. I recently had my Mirena taken out in early May. I started doing ovulation tests, because I had no idea when my last period was, and hit high fertility but never peak fertility. AF is 5 days late(if I count the day the iud was taken out as AF, I was spotting the morning but once it was out I stopped spotting). Yet all test say I’m not pregnant. I’ve taken 3 home test in the past week, today being the last. Any suggestions on what to do or what to think? Idk if I should start the ovulation tests again or wait for AF. How can I get my cycle to regulate faster? I’ve been told it could take months. Does anyone have experience with this? Help! All advice or suggestions welcome!
