Early ovulation.....

Merrill

I decided to start using my ovulation strips on cycle day 9 (December 30) and my test line was almost as dark as the control. I didn’t think much of it because it was so early and I typically ovulate on average around cycle day 17. I didn’t test again until January 2nd and that was high but not a surge. Since then the tests have been low. Could I have ovulated sometime around the new year??? I’m now on cycle day 16 and my lines are getting fainter. I typically have very regular cycles but unsure if that has anything to do with ovulation regularity. TIA for any input!!!
