Hi Peanut, welcome to the forum 🙂 I'm no expert on pregnancy and how your blood sugars might behave in the few weeks afterwards, but you do cite a couple of meals that would send my blood sugar levels sky-rocketing, and the same with pizza. Your one-hour post-Weetabix, whilst a little on the high side, isn't too bad at all. Have you tested before eating as well, so you can measure the actual increase caused by the food? I'd be more inclined to take note of waking levels, ad you say yours was 4.6 prior to the OGTT, which is very good. Also the OGTT is designed to give your system a really hard wallop of glucose to see how it copes - again, yours coped reasonably well, at only 1 mmol/l above the 'diabetic' threshold of 11 mmol/l. Your HbA1c is that of a person without diabetes.
It may be simply those post-pregnancy hormones still at play, and it may settle down, but you are wise to pay close attention to it all the same. It may be a very early onset of LADA - that can manifest itself very slowly indeed, sometimes over years. The antibody test should show what is happening, although I think it can be inconclusive sometimes. There is another test called the C-peptide test which measures the amount of insulin your pancreas is producing - do you know if you will be tested for this also?
