I am getting really discouraged....

We found out last year that my husband has azoospermia (zero sperm count) so we decided to go ahead with a donor. First IUI cycle was supposed to be this Feb. Went for my follicle scan and I had a MASSIVE cyst on my right ovary, so Feb was out. Rescanned in March and it had shrunk considerably (6cm to 2cm) but dr wanted it smaller, so March was out. Rescanned today (cd3) and now I have a cyst on the left side so now April is out. I am getting really discouraged and feeling like it's never going to happen. Any words of wisdom?
