Any suggestions

So my drs switched me from metformin & another pill I was taking to metformin and insulin. But it seems like the insulin is not working at all! My numbers are higher than they were before. I’m getting nervous bc I don’t want my numbers to be out of range and hurt the baby! I checked my numbers and they were 142 2 hours after breakfast, I checked an hour later and it’s only 130. When I wasn’t on insulin it was lower.
