I'm TTC no.3 and have PCOS. Somehow got pg with DC1 without help, with cycles 45-60 days long. Dc2 was conceived on cycle 7 but we paid for a private referral and I was given metformin which I was only on for a month and then conceived. I've been tracking my cycles and reckon my luteal phase is only around 10 days, cycle length 30 days. I'd like to give metformin a try again but without having to pay about £200 for a private referral. Does anyone know if a GP would prescibe it if previous proof of PCOS, blood tests etc etc?
