Clomid isn't necessarily the miracle drug

So I have done three cycles on 50 milligrams and 2 rounds on 100 milligrams and still not pregnant. From what I read if you don't get pregnant after six cycles with clomid chances are you won't. So at this point I feel that clomid is not working for me. I fear that doctor is going to suggest IVF which I know is expensive. I am so disappointed and feel so defeated. Overall I am just heart broken.
