question: Hi, I had my follicular study on the 12th day. The left ovary follicles measured F1 - 18.4 mm, F2 15.5 mm., The right ovary follicles measured F1 14.1 mm, F2 13.8 mm and the endometrial thickness is 9.4 mm., Please can you let me know if this is normal? also please can you let me know my likely fertile period?
