Hospital Appointment

Hi all
Myself and my partner have been TTC for 17 months now, my periods stopped 5 months ago, I have pcos and type 1 diabetes. We have our first appointment with the gynocolgist in the morning for help to conceive. I've read that they prescribe Clomid & Metformin, however unsure if I'll be able to take Metformin as I am insulin dependant. Does anyone know what happens at the appointment? I am a little nervous xx
