PCOS And Metformin

I have Type One Diabetes and I have recently been diagnosed with PCOS. I have an appointment in a few weeks with my gyno to figure out what comes next, but I have been doing some research in the meantime and had a few questions for anyone who has been in a similar situation...

I have read that Metformin can be taken to help with weight loss (and thus decreasing the PCOS symptoms.) How does this work when you have type one?

Thanks in advance! I'm a bit clueless with this situation and would love to hear how your story played out!
