If ovulation is delayed by 5 days, will menstruation also be delayed?

Patient's question:

No

Doctor's answer:

Irregular menstrual cycles can also lead to inaccurate calculation of ovulation periods. You can opt for ultrasound monitoring of ovulation. On the 9th day of your menstrual cycle, go to the hospital for monitoring. Generally, it is done 3-5 times, and the doctor will inform you of the accurate time of ovulation.
