Metformin??

Jordan • Had our first on April 13, 2016 and she's my everything
So I'm on my second round of Clomid... First round I didn't ovulate "well"
So this time I had to start all over... Provera for 10 days to start AF... Then Clomid days 5-9... But this time my doc has given me Metformin... And she said to take it right away... Anyone taken Metformin? How did it help/not help you? And your side effect of any?
