Is this ovulation?

I started taking pre conception tablets a few weeks ago as my doctor said it could help regulate my cycles. My cycles usually last between 40-45 days but they have been really irregular lately.

I started my period on the 16/12 and finished 21/12. I started taking these tests in the morning and evening on Christmas Day.

Would you say I’ve ovulated by looking at these tests? Is it possible to ovulate this early? Thoughts?? Thank you!!🙂
