How accurate is an ovulation test strip?

Patient's question:

No

Doctor's answer:

Ovulation test strips are not early pregnancy test strips. If your menstrual cycle is less than 21 days or more than 40 days, please consult a specialist. After ovulation, if the egg is not fertilized, you will definitely have your period 14 days after ovulation. For people with a relatively regular menstrual cycle, counting 14 days backward from the first day of the next period should be the day of ovulation.
