Occurrence of ovulation is mandatory for assurance of pregnancy. Follicular tracking is considered necessary to develop better understanding of their ovulatory pattern. Cycle monitoring involves serial ultrasound scans at regular intervals until we consider ovulation imminent. Sometimes patients are advised blood tests to corroborate clinical and ultrasound scan findings. This approach helps us develop an in-depth understanding of the physiological menstrual cycle (MC), ovulation, LP, hormonal change during the natural cycle.
