The main "con" is that adjusting to it can cause major stomach upset. I would recommend when you start it and each time you increase, you do so on a weekend or other time you have at least a day or two where you can be close to a bathroom. Metformin may aid weight loss, although in my experience the majority of that loss is in the first few weeks as the body goes through the adjustment and the patient ends up unable to eat much due to the GI side effects. Most women need to be on the full dosage at least 2-3 months before they see a change in cycles.
Thus far, there have been no studies showing serious negative side effects of Metformin. At worst, it simply doesn't induce ovulation.
