Monitoring ovulation with ultrasound for women with regular menstrual cycles is generally recommended to be done from day 10 of the menstrual cycle.
The use of ultrasound to monitor and observe follicular growth to guide the timing of intercourse is called follicular monitoring or ultrasound monitoring of ovulation.
For women who have regular menstrual cycles, usually having 1 period around 28~30, and the day of ovulation is usually around 14 days before the next menstrual period, the ovulation period can be counted from the 10th day of the menstrual cycle. Therefore, it is appropriate to start ultrasound at this time to monitor the growth of follicles.
For women who have an urgent need to get pregnant and want to find the exact time of ovulation, ultrasound monitoring of ovulation is a better method. For women with irregular menstrual cycles, it is recommended to go to the gynecology department of the hospital to find out the cause before monitoring ovulation.
