Hey,
I'm 19 weeks 2nd pregnancy.
On Metformin 1g twice a day humalog with every meal and then levimir at night although I anticipate that with change to twice a day like it did last time. Im afraid I have never been on Diamicron. Pre conception I saw a high risk obstetrician who reviewed all my drugs to let me know what ones I needed to change. Now I see that high risk obstetrician and a diabetic consultant every 2 weeks who review everything.
I'm sure your gynaecologist is fully aware and informed but you should start seeing the people very soon and very regularly
