you need to find a new doctor!
If you are not ovulating then you wont get pregnant. I had periods every 3 or 4 months and dont believe I ovulated at all until I started taking metformin.
I would hate to see you waste time in this. If you are sure you dont ovulate often then you will need something to help you do that. Clomid worked for me first try but ended in MC, I am currently on my second round of clomid. There is only a very small chance of multiples. And for me and most others, multiples are much better then nothing!! I would love to have multiples, as long as they were safe and healthy, I know risks are higher with multiples.
