I was doing every three months after getting established. Now, it seems my doctor wants every 6 months. This may change, however, as I'm going to see a new doctor for a consult in order to discuss switching from pills to injections. As for results, pay attention to your levels because that's important; although, keep in mind that they fluctuate. MY e levels went from 110-120, 70 to 140 with doing nothing different. Just make sure they are in the proper range in general (for example, 70 is way too low).
