Prior to commencing the egg freezing process, it's important to discontinue the use of birth control pills or patches since these methods prevent ovulation. However, you can resume their use after the egg retrieval procedure. If you have an IUD, it's not necessary to remove it during the egg freezing process. For individuals who have been using birth control pills or patches for an extended period, we often recommend a one-month "rest" period—essentially a month off from birth control. This recommendation is made because the pill essentially causes your ovaries to enter a dormant state. To enhance your response to fertility medications, we suggest this extra month without birth control to allow your ovaries to awaken. Opting not to take this month off is absolutely acceptable and won't affect the outcome negatively; however, it might extend the duration of the egg freezing cycle, resulting in additional days of medication to stimulate your ovaries.
