$28 for a 3 month supply doesn't seem right. I am guessing it is at least double that at the very minimum given my own prescription. You may be able to go to a public health clinic where they sell birth control at a lower cost than a doctor's office but not sure if they will see you without a health card. I would call around because some doctors will want a full exam before renewing your prescription. I would budget $100-150 for the appointment and prescription.
