Doctor's answer:

For ovulation test strips, the results may not always be accurate. It's better to undergo an ultrasound examination to check the ovulation status, which is more reliable. Generally, testing should begin around the 10th day of the menstrual cycle to monitor the development of the follicles and determine if ovulation has occurred.
