I am 2 weeks into my life as a 'diabetic' after being diagnosed with GD recently and posted a very similar thread myself. Honestly, for me it has been far less scary and traumatic then I thought it would be when I first got the phone call. The dietician will talk you through GD friendly alternatives to normal every day foods but it's pretty straight forward - wholemeal instead of white bread, no sugary foods, not too much 'starchy' foods like mash potato. She did go on to say that for many woman in the first few days it's complete trial and error and what will increase glucose levels for me might not increase yours. E.g. I CAN get away with a chocolate biscuit or a few blocks of dairy milk but I can't eat white bread or more than a slice of bread in one sitting.
In the past 2 weeks I've had 2 high blood sugar readings - one caused by porridge and honey (silly choice on my part!) and the other was caused by two slices of thick wholemeal toast. Exercise helps keep levels low so when I did get a high reading I just went for a 15 walk around the house (it was chucking it down) and it dropped right back in to normal range.
I take bloods first thing in a morning (fasting), after breakfast, after lunch and after my evening meal. The finger prick-er really doesn't hurt, infact I can barely feel it most of the time.
We had an extra growth scan this week (which you'll be offered) and baby is absolutely normal - I'm not growing a monster and his weight and measurements are average. Consultant is now happy for us to go to 39 weeks of everything remains as it is and diebetes team see me once every 4 weeks.
I know every single woman is different and this won't be the same for everyone but I thought I'd share my experience. If anything it was a blessing in disguise, a little shove to stop eating that extra serving or ice cream or that extra chocolate biscuit. Oh and for what it's worth I don't fall into ANY of the risk categories, no past history, no high BMI etc...it was purely an administration error which resulted in me going for my GTT, but Im glad I did.
