Patients often switch from one contraceptive method to another. For example, a patient who has trouble remembering to take a pill daily may change from an oral contraceptive to an implant.
To minimize the risk of an unintended pregnancy, patients should avoid gaps between methods. That is, patients should go straight from one method to the other without waiting for a period. In some cases, overlap should occur between the old method and the new one. Backup methods (such as spermicide or condoms) are a good idea if a patient does not want to have overlap between the old method and the new method.
