Hey, I had similar fasting readings after increasing my metformin to 2 tabs. Got quite worried and spoke to my dietitian and midwife, they both said it’s fine and to only worry if it’s higher than 5.3 x
I actually mentioned my levels were 3.1 to my diabetes nurse, and she said they don't worry about low numbers with GDM, only high. Xx
I was the same, the only care about low numbers if your on insulin, just anything that's high xx
I'd contact them if you're worried, I loved curry with lots of protein and veg with cauliflower rice instead x
