Fasting levels?

Hi I was diagnosed prediabetic in December with a fasting glucose of 6.1 and hba1c of 46 having had gestational diabetes twice. I have been monitoring my blood since and cutting out a lot of carbs. What has concerned me is my high fasting compared to the levels the doctors saw, they seem to be getting worse, I had one of 8.9 yesterday which is ridiculous,should this be a cause for concern to go back to the doctor? I understand the whole dawn phenomenon but it is normally taken before breakfast and is consistently high and high after breakfast as well, I always had very low numbers when I had gd (<5) so this seems quite unusual to me. All my other readings through the day seem fine. Just worried it's developed more into type 2 as been an it 6 weeks since bloods were done.

I'm doing ok,had a few blips, managing well with the yoghurt for breakfast and seeds or just eggs,it's the evenings I struggle with as still have Xmas snacks! I am trying the 8 week blood sugar diet although to a slightly more calorie one to start!

Thanks my lunch and evening meals are generally fine it's just morning and after breakfast is the problem, just worried how it's gone up obviously in the 3 weeks I've been taking readings!
