Depending on a few factors, there's a few things you can try. How far long are you? Do you use a pump or needles?
If you're higher before meals and going low after meals, you probably don't need to be correcting those pre-meal readings, but instead, trying to get your numbers lower in the couple of hours before you eat - so whatever is going on 2-4 hours before you eat probably needs to be changed. If you're pumping, raising the basal rate slightly. And if you're on needles, perhaps raising up your longer acting.
I would try to stop correcting at the meals and see how that goes and just concentrate on getting the pre-meal numbers down much farther in advance of eating. You may find that your meal ratios start to change too - if you stop correcting the higher numbers and are still going low after eating you might want to try a bigger ratio (ex: 1:10 vs 1:5).
Don't know how far along you are, but I didn't feel my anxiety about pregnancy easing up until the 2nd trimester and spent most of my first feeling frustrated, angry, and anxious. I don't think it's unusual - there's a lot more to think about than a lower risk pregnancy.
