False positive ovulation test 🤔

SO and I have decided to try for our first bundle of joy. I was on the nuvaring for 4 years due to having irregular periods and not wanting any kids. Well I finally stopped September 3. AF was due Oct. 7. waited a week and got a bfn. So 14 days later I decided to test for ovulation. It was positive... How is it possible if AF didn't show her ugly face? Could I have gotten a false positive? Even though I dislike AF I'm now anxiously waiting for her to show her ugly face. Any tips on how to make AF come? Thank you in advance! Baby dust to all!
