I started my 3rd round of Clomid this month, but the first month on 100mg (day 5-9). I had an ultrasound today (Tuesday/day 14) which showed a few very small follicles on my right ovary but on the left were about 4 or 5 that measured about 1.4 and 1.5. Last month I didn't have a mature follicle at all. My doctor wants me to come back on Thursday (day 16) for another ultrasound to see if they have grown. Dr. Q, how much do follicles grow in a day? Do you think they will be mature in just 2 days?
