I was on clomid about a year and a half ago (only 1 cycle) I did not ovulate at all. I was also on Clomid 2 1/2 years ago (3 cycles) and did not ovulate then either. I am now on Metformin and clomid that I just started this month. Has anyone had clomid constantly fail them, but then when trying again months or years later it did help? I don't ovulate at all and I have PCOS; any positive stories would be great
