@AliceRR I've not spoken to the MW yet. It comes and goes, but if it gets as bad as yesterday then I might have to. I've done a lot of driving the last couple days so I think that's aggravated it.
I think the GD test is only if you're classed as high risk -
your body mass index (BMI) is above 30
you previously had a baby who weighed 4.5kg (10lbs) or more at birth
you had gestational diabetes in a previous pregnancy
one of your parents or siblings has diabetes
your family origins are south Asian, Chinese, African-Caribbean or Middle Eastern
