In majority of couples, you need to come to clinic only three times for follicular monitoring.
Ist ultrasound is done on day 2nd or 3rd day of periods (day 1 is day of onset of menstruation) In this we study the baseline pelvic organs. Uterine lining should be thin and ovaries should be in silent state i.e. no cyst or dominant follicle more than 10 mm is present.
If this is your first pelvic ultrasound then it gives us additional knowledge about any uterine pathology like fibroid, adenomyosis or ovarian cyst. We can also rule, out any tubal pathology and ovarian localization.
IInd ultrasound is done on day 10 or day 11 of periods. The size and number of developing follicles is noted, Endometrial thickness is also recorded. The approximate day of rupture of follicle can be calculated from this ultrasound.
IIIrd ultrasound is done on approximate day of rupture to confirm the same.
