Absolutely! You will be empowered to manage your fertility to either avoid or achieve a pregnancy, however you and your spouse choose to do so. When the CrMS is used exactly as instructed to avoid pregnancy, yearly pregnancy rates can be less than 1%. Accounting for errors in teaching or use, yearly pregnancy rates are about 4%.

To reach this level of effectiveness, you need to meet your Creighton Model Practitioner for regularly scheduled followups. You also need to recognize that if you choose to have intercourse on a fertile day on the CrMS chart, pregnancy is highly likely.
