I would like to ask the doctor if I took RU486 on May 7 and May 9, and had unprotected intercourse during that period, as well as on May 10 without protection.
I would like to know if there is still a possibility of pregnancy.

After taking the abortion medication, you should return for a follow-up appointment within 1 to 2 weeks.
Please consult your attending physician at that time.
Thank you.

More Info

RU486, also known as mifepristone, is a medication used for medical abortion. It works by blocking the hormone progesterone, which is necessary for the maintenance of pregnancy. When taken in combination with another medication, misoprostol, it can effectively terminate an early pregnancy. However, there are several important considerations and potential risks associated with its use, particularly regarding future pregnancies.

First and foremost, it is crucial to understand that RU486 is typically prescribed within the first 10 weeks of pregnancy. The use of this medication should always be supervised by a healthcare professional to ensure safety and effectiveness. After taking RU486, it is common for individuals to experience side effects such as cramping, bleeding, and nausea. These symptoms can vary in intensity and duration, and in some cases, they may require medical attention, especially if there is excessive bleeding or severe pain.

In your specific case, you mentioned having unprotected intercourse after taking RU486 on May 7 and May 9. It is essential to clarify whether you have confirmed that the abortion was successful. After taking RU486, it is recommended to follow up with a healthcare provider to ensure that the pregnancy has been completely terminated. If the abortion is incomplete, there is a risk of continuing the pregnancy, which could lead to complications.

Regarding the risk of becoming pregnant after using RU486, it is important to note that while the medication is effective in terminating a pregnancy, it does not provide any contraceptive protection. If you engage in unprotected intercourse after taking RU486, there is a possibility of becoming pregnant again. The timing of ovulation plays a significant role in this scenario. If you have already experienced a complete abortion and your menstrual cycle has not yet returned to normal, you may still be at risk of ovulating and conceiving.

If you are concerned about the possibility of becoming pregnant after using RU486, it is advisable to consult with your healthcare provider. They can provide guidance on the appropriate steps to take, including the use of emergency contraception if necessary. Emergency contraceptive pills are most effective when taken within 72 hours after unprotected intercourse, but some types can be effective up to five days later.

In summary, while RU486 is an effective method for terminating early pregnancies, it does not prevent future pregnancies. If you have had unprotected intercourse after taking RU486, there is a risk of becoming pregnant again. It is crucial to follow up with your healthcare provider to confirm the success of the abortion and discuss any concerns regarding future pregnancies or contraceptive options. Always prioritize open communication with your healthcare provider to ensure your reproductive health is managed safely and effectively.
