Suz - yay at the referral for Dr Pardey! He's awesome. Just be warned - he will probably send you for all the same tests again anyway. He did with us.

I didn't get a bleed until about 6 weeks into Metformin. I did 2 weeks of 1 tablet a day, then upped it to 2 a day (I didn't get any side effects) Dr Pardey ordered a BT for day 21 to see if I O'd ... and it showed I was about to O.. and that actually matched my FF chart So it was a long cycle that first one. So don't be disheartened if it takes a bit longer than a couple of weeks.

Good luck! Makes you feel so much better when you feel like you're finally doing something about it huh.
