Hi anyone please provide your feedback on IUI follicle size, today I did USG 18th day Left side one  follicle size is 18*12mm and another one is 12*8mm, endometrium is13.7mm and no FF they mentioned, my doctor said the follicle shape is elliptic there should be only 2 to 4mm difference between the length and breadth but it's 6mm difference and said could not continue with th IUI in this cycle. Just wanted to confirm if this is is correct statement as I referred many queries related to this and never seen such statement anywhere. attached my US report below
