2nd Unexplained Infertility

I am so upset and at the moment feel like giving up my dream. I had an appointment with my doctor today to discuss more aggresive treatment since I did 3 rounds of clomid to no avail. I did respond very well to clomid as I had 4 mature follicles each time. In fact my doctor did an ultrasound today and told me that i have cysts due to hyper stimulation. I told him that I want to move to IUI and he did not encourage me at all. He said that I have unexplaine infertility since all is well with me and my dh and iui is not really going to improve my chances considering that my dh's last sa showed 66million sperm count and 75% motility. He told me that I should give up my dream because I am getting obsessed and stressing my dh and ds. I am so upset. He told me that most probably I will not be able to do iui this cycle because of the cysts because they have to go away in able to take clomid. He told me to have an ultrasound on cd 1 to check about the cysts and then proceed from there. He told me to think twice about the steps I am taking because as if it was for him he won't do what I am doing. I don't know what to do! Please give me your opinion!
