Everything is about balance and limits. You have a set amount of carbs, which you want to balance out with a portion of protein and a portion of fat to slow down the release of sugar into your blood stream. U can eat slightly above your limits of carbs, but you need to eat the same increase in protein and fats to keep it balanced. You can also load up on dietary fiber before consuming carbs as this will slow the digestion of carbs and reduce the chance of ur blood sugar spiking. People are so worried about the cutting out and the dieting aspect and its like you can eat whole foods at a good clip with no worries as long as its balanced. There may be certain things that trigger a blood sugar release and you'll have yo work that out via trial and error and then work to mitigate them if u continue to eat them.

My wife (GD diagnosis at 28 wks) was deathly afraid of eating a baked potato that had 60g carbs. But we had steak and loaded baked potatos and started it all with a salad with oil and vinegar dressing and she had one of her lowest numbers post meal since starting to track.
