i had my first 3 dd's in hospital. with my 3rd i had gestional diabetes, which was managed with diet alone. was induced 2 weeks early, and she spent 24 hrs in SCBU being tube fed.
before i fell pregnant with dd4, i lost just over a stone. i DIDN@T have GD, and had a lovely problem free pregnancy and delivery at home.
with this pregnancy, i have lost another fuirther stone before falling pregnant, and have gained a whopping 4lbs of weight by 29 weeks. 
so am doing ok. I am managing my diet the same way i did with dd3, despite have severe morning sickness which is still ongoing.
i have refused to have a GTT done, as aM still being voilently sick most days, especially before lunchtime, and need to eat and drink in the mornings. i know i woldnt be able to tolerate getting kiddos to school, not eating, getting to hospital, drinking that stuff, and waiting for 2hours.
I have however agreed to a random blood sugars test, which does involve fasting, but no drink, and no waiting an extra 2 hours.
I am hoping this wont go against my homebirth plans.
