Type 1, 22 weeks, insulin resistance and metformin

Hiya wondered if any other T1 mums or mums to be had had this suggested to them?

I'm currently 22 weeks and take approx 140 units a day (100 novorapid, 40 lantus) it's a significant increase from my low carb days and pre pregnancy amounts. The diabetic doc at the hospital has suggested that in a few weeks due to the large amount of insulin I am taking and the high chance that it will increase over the next few weeks that she may put me on metformin alongside my insulin. (this is the third doc I've seen during the 22 weeks and the only one to mention insulin resistance and metformin!!)

I wouldn't have a problem with this, I know what metformin does but the NHS website states that you should not take metformin whilst pregnant. I know the docs know what they are doing (I hope) but sometimes I feel they talk to me like I have gestational diabetes and that altering doses, carb counting etc is something new (which it certainly isn't!!!)

My HB is 28 at the mo or 4.7%, blood sugars fine and all ok at the 20 week scan.

Was/has any other T1s prescribed it during pregnancy and or what are your thoughts/comments??

Thank you both for replying/bumping to you both. Good to hear someone else who is pregnant and on it

I'm now 26 weeks and on 2 x 500mg twice a day. It has reduce my insulin novorapid intake dramatically though so feeling happier.

I am feeling a little bit sicky though, don't know if it's the meds or the acid reflux though - the joys
