Ginger. How annoying. I would love to let these people try it for a week, especially when pregnant, and see how easy they find it. Idiot! Consultants like that are why people start 'massaging' the results in their little books!! I cannot stand being patronised - makes me seethe. Incidentally, 6.2 is a great third trimester hba1c, you are obv doing a great job. 
I've been having lots of weird afternoon lows. Yesterday had a sandwich for lunch with no insulin and was still low two hours later. Think it is the heat but will also need to drop the daytime levemir down.
Morning readings not quite so catastrophic but still not great. Working on them...
