Metformin, What to expect? ADVICE PLEASE.

Co

I finally went to the Drs today after having 7 periods this year and not ovulating.

She was so sympathetic and prescribed me Metformin (1 pill in the morning for 1 week then 2 a day for a week then 3 a day )

Shes got me ready for blood tests.

Amd ultrasounds..

But what should I expect with This medications?

What should I avoid eating/doing ?
