Any advice please...

I came off birth control at the beginning of Dec after years on it as we are wanting to TTC.

I had my first bleed on 2nd January that lasted 5 days. It arrived 1 day late (I always have been super regular, 28 day cycle)

According to One Step ovulation tests I didn’t ovulate in December and I haven’t ovulated this month but we are still BD every other day in my fertile window.

Does anyone have any experience with delayed ovulation after coming off the pill?

Thank you!!
