Not sure how to get enough carbs without spiking? Feeling defeated.

I was diagnosed just over a week ago at 32 weeks pregnant and have been managing it through diet and exercise for now while we monitor my food log and numbers. I’ve been keeping my numbers within range all week (even over New Years!) and was really proud of myself, but I just had my first appointment with my endocrinologist and she says she’s worried I’m not getting enough carbohydrates with my meals. I’m definitely getting plenty of food, but I do keep my carb intake around 15-30g per meal most of the time or else my numbers spike. She wants me getting 45g with lunch and dinner, but when I said that would spike my numbers she said if that happens we would introduce insulin. I guess I’m just frustrated- I realize it’s only been a week but I’m already sick of constantly thinking about macros. I thought I was doing well and I feel so defeated.

I also feel like it’s throwing me back into a disordered eating mindset, like meals and macros are all I can think about again. I did not grow up in a very body positive environment and i can’t remember a time when I didn’t ‘struggle’ with my weight. I finally got into a more healthy mindset in the past 2 years and honestly the first two trimesters of pregnancy had been the best months I can ever remember as far as my relationship with food goes. I might not have been eating super healthy all the time but for once I didn’t associate food with guilt or being a reward - it was about nourishing myself and my baby. I felt like my body was doing something amazing and feeding it intuitively was natural - if I was hungry I ate, if I wanted chocolate I had some and didn’t stress about it.

I know the feedback at the appointment wasn’t even bad, but now I’m spiralling. I feel like my whole world is centred around blood sugar levels and counting macros again and i’m failing, and not just myself this time but my baby too. Can someone talk me off the ledge please?
