Emergency Contraceptive Pills After Uterine Surgery - Obstetrics and Gynecology

More Info

---

After undergoing a uterine surgery, such as a hysteroscopy, it is important to understand how to manage your contraceptive methods, especially if you have been using hormonal birth control like the 28-day pill pack.
In your case, since you had the surgery on May 27 and your doctor advised you to continue taking your birth control pills, you should follow the same regimen as before. The hormonal contraceptive pills work by maintaining consistent hormone levels in your body, which helps prevent ovulation and thus reduces the risk of pregnancy.
When it comes to your menstrual cycle (MC) after surgery, it is important to note that the timing of your next period may be affected by the surgery itself, as well as by the hormonal contraceptives you are taking. Generally, if you are on a 28-day pill pack, you would take the last active pill in the pack and then have a withdrawal bleed (which mimics a period) during the placebo week (the last 7 pills, which are typically inactive).
If you are asking whether to start a new pack after your withdrawal bleed, the answer is yes. You would start the new pack immediately after finishing the placebo pills, regardless of whether your period has started or not. This ensures that you maintain the contraceptive effect of the pills.
Regarding the effectiveness of the birth control pills after your surgery, as long as you have been taking them consistently without missing any doses, you should still have contraceptive protection. The hormonal pills do not lose their effectiveness due to the surgery, and they will continue to provide protection against pregnancy as long as you take them correctly.

It is also worth noting that some women may experience changes in their menstrual cycle after surgery, including lighter or irregular periods, especially if the surgery involved the uterus. However, this does not necessarily indicate a loss of contraceptive efficacy.
If you have any concerns about your menstrual cycle or the effectiveness of your birth control after surgery, it is always best to consult with your healthcare provider. They can provide personalized advice based on your medical history and the specifics of your surgery.
In summary, continue taking your birth control pills as prescribed, expect your withdrawal bleed during the placebo week, and start a new pack afterward. Your contraceptive protection should remain intact as long as you adhere to your pill regimen. If you experience any unusual symptoms or have further questions, do not hesitate to reach out to your doctor for clarification and guidance.
