hi linda
im not too sure about your steriod shot but dont stress that this is anything you have done - i tried to control my gestational diabetes with diet but it didnt work (& i stuck to exactly what they told me) so am now on insulin & still getting used to keeping it under control - it is mainly the way the baby reacts with the pg hormones so having a sweet tooth (like i do) will just have to be put into moderation - good luck with your test
