[|Human|] Hello Doctor, I had a dominant follicle on cycle Day 10 in right ovary but on day 13, my doctor says there is no dominant follicle in any of the ovaries... I have 28-29 days of cycle...I am so confused... plz tell me how it is possible that dominant follicle disappears.
[|AI|]  What was the size of the dominant follicle on day 10. Were the two ultrasounds done by the same doctor? The fact that it was not seen on day 13 means that you have ovulated (the follicle must have ruptured). In all probability this is the reason. So don't worry. A small possibility is that the first ultrasound itself was wrong and that there was no dominant follicle in the first ultrasound. See your doctor and Check for serum Progesterone on day 20-21. The result will confirm whether ovulation has occurred. If you have any further concerns do write to me. I will be happy o answer.
