Is it possible to find a doctor that I don't have to go see every month (see details)?

At the beginning of this year I began seeing a nurse practitioner at a doctor’s office regularly for hypothyroid. Since I became pregnant in May, I’ve had to get blood work once a month, and go for consultation a few days later, every month. The frequency of the doctor visits seems to be unnecessary to me. I’m very grateful to have health insurance to cover it all.

Why can’t she just call me if my tests results have changed, then either change my prescription or have me come in then. I really don’t mind coming in every couple months. But especially now that I’m pregnant, it seems that I’ve got a doctor’s appointment or blood test or pharmacy drop off/pick up every couple days.

So, is every doctor going to insist that I come in after each blood test? All my current NP does is take my blood pressure and check my thyroid to make sure I’m not getting a goiter. Is it standard to do this every month?
