Definitely time for a different doc, or get ready for a battle for proper treatment. Anyone here will tell you that. Most MD's will staunchly stick to a 2-3 week interval for injections even though this is long outdated and shown to cause a whole bag of terrible side effects. It took a few appointments of me bringing pubmed articles and personal accounts in support of a shorter interval of 1-2 shots a week before my endo finally gave in to letting me inject 100mg once a week. I've felt 100x better since switching to this from 200mg every 3 weeks. Its worth it to find a doc who's willing to work with you.
