Hi, was wondering if anyone had experience with actually falling pg through being helped with Metformin and how long it was before you stopped taking it?

My specialist who put me on Met didn't tell me what to do if I actually fell pg, and he is away for another week and a half. I saw my GP yesterday to get a BT to confirm pg (I think I'm 5 weeks 3 days) and when I told him I was taking Met he said 'stop it now, you mustn't take it in pg'. But I've read on the internet about small studies showing that women who continue to take Met to 12 weeks have a smaller m/c rate (as it is much higher normally for women with PCOS).

Help. Any info appreciated. Despite what my GP said, I'm still taking it until I find out properly.
