Ovulation needs to be measured continuously, there is no such thing as when it is best to measure. Ovulation can be monitored using ovulation test strips or by ultrasound. Ovulation can be detected using morning urine from the 11th day of menstruation until a strong positive is detected, and then every 4 hours, after ovulation, the test will turn weakly positive. For women with regular menstrual cycles, ovulation monitoring usually starts on the 10th day of menstruation, and is monitored every other day until a mature follicle appears. If the follicle ruptures, ovulation has occurred, and coitus can be arranged to increase the chances of pregnancy. Monitoring ovulation is not just once, it needs to be done several times to find out the time of ovulation, women should also relax when monitoring ovulation, don’t be nervous and anxious, so as not to affect the pregnancy.
