As you know each month ovulation occurs from one of the ovaries. Egg is present within the growing follicle and for complete maturity of egg, follicular size should be more than 18mm. In your case on 10 th day it is 16*12 ( mean 14mm). Usually follicle grows 1-2 mm/day. Here follicular size has not increased from 10th to 12th day. Endometrial thickness of 7.6mm is good. NDF means no dominant follicle in left ovary. Dont worry just continue with the same treatment n get ultrasound
done after 2 days. Take care.
