Ah, Metformin. You probably already stated that in the thread. Sorry. It's a really widely prescribed drug, and like most drugs on the market, it has risks (I learned in recent years that one of my insulins is not yet considered a safe drug!). Are you going through the private or public system? You might find a useful source of info is a diabetes educator, as well as an endocrinologist. Educators are a godsend to me with pregnancy and I can't think of a single time they haven't known what to do and how to do it quickly. That's the pro and con of diabetes in pregnancy - both that it is within a limited time frame, and that it is a limited time frame! Any longterm problems are not likely to matter as much, but then again you only have a few months to master perfect control so that bub doesn't gain excess weight and have issues at birth with low bsl, etc.

If you're after just personal opinions, I'd not be too afraid of the Metformin. It's a short term plan only. That said though, don't be bullied into anything that you just can't be confident with - and that goes for info on the internet, or from a well meaning doctor who is asking you to swing the impossible and be textbook managed!
