At first I tried ovulation kits, but my periods were just too irregular.
For my first child, my Dr put me on
metformin. While on that, my periods became a little more regular at every 6 weeks. For this pregnancy, I first tried clomid. That didn't work so I was switched to letrozole. I had just given up on that to go back to metformin, but find out I was pregnant. Good luck!
