I didn't take Clomid, but I did have to take artificial hormones and they put my blood sugar right up. I had to have more insulin for my boluses and adjusted my basals slightly too (I'm on a pump). It was frightening to start with, but I gradually realised what my new pattern was and so I was able to adjust my insulin to keep my blood sugars down. I did a lot of corrective doses at the beginning.
However, I think I'm right in saying that Clomid is only taken for a few days each month? If that's the case, then you'd have to be very careful about any adjustments. All you can do is test, test and correct. Then maybe speak to your DSN and come up with a plan for adjusting insulin doses if that was needed.
Best of luck : )
