🤔 hmm late ovulation?

So I got my period December 18-23 and I started my ovulation test around December 28

My three apps said my ovulation day was around January 3rd /4th (I do not track my temp)

My eve app said my fertility week at 30th-6th

I did all my testing and I got almost positive ones on January 4th missed Jan 5th and the 6th the test were low so I figured it just missed it this month but ...

I randomly decided to take a ovulation test today 4 days past and it was positive

Could it just mean I ovulated late?

My cycle is always on time or if anything it’s late by a day
