Mody is so rare but I hope you find some support!
The drug you have been given is one which encourages your body to make extra insulin which is why you are having hypos.
This is an old drug but nothing new is tested in pregnant women for obvious reasons.
All I can say having been pregnant x 3 is that by the middle of it you should be naturally a lot more insulin resistant and so won't get the hypos.
I appreciate that with a toddler too geting up for hypos is tiring. Do you have an fsl.
The other thing to say is that the hypos are a nuisance but shouldn't harm the baby which was something which I worried about when I had them in early pregnancy.
