Hi @alicein_wonderland. Welcome to Connect! Sorry to hear what you are going through. I too have PCOS and I do take Metformin. I think it helps a lot, however i’m also on birth control, so it’s hard to tell which is helping (likely some combination of the two). The only negative side effect i’ve had is that it did tend to upset my stomach, but taking it with food and going to the extended release version seemed to help with that. I understand the inclination to not was to add another medication, but if your PCP thinks it’s a good idea, it might be worth a shot. I also see an endocrinologist for my PCOS. Are you seeing an endocrinologist? Has that ever been suggested?
