Hello
@Isobelgr93
Firstly congratulations, particularly after all the hard work you've done to get to this point.
I was gestational with my daughter, so didn't have t1 prior to pregnancy, I don't know at which point the tide turned but I was diagnosed at 23 weeks and the rest of my pregnancy was on insulin, my best advice is to not panic, getting anxious doesn't do you or baby any good, there's alot going on with your body and hormones and the swinging levels will only be made worse if you're stressing too. If you can keep a paper diary and record your levels/insulin taken/carbs eaten it will help to give you a better perspective in regards to seeing some patterns. As your body changes so does your insulin needs so recording information is good if you're feeling out of control with your levels.
What insulins are you taking, do you use a Libre ?
