1. When does follicle monitoring start?

For women with regular menstrual periods, no matter the length of the menstrual cycle, as long as the menstruation is on time and the interval between two menstrual cycles is no more than 7 days, the ovulation period is generally about 14 days before the menstrual period. For women with normal menstruation, the corpus luteum deficiency lasts for about 14 days, the corpus luteum shrinks, the function decreases, and menstruation begins. Therefore, the follicular phase is fixed, but the length of the follicular phase may be uneven.

What should women with irregular menstruation do? It is recommended to start monitoring follicles from the third day of the menstrual period, and interrupt or continue long-term monitoring. Because the follicular phase and the physiological period cannot be clearly distinguished, the monitoring time should be increased at this time.
