Questions after taking RU?


Hello Doctor, my girlfriend took RU486 and did not experience heavy bleeding; instead, she had only light, thick, coffee-colored discharge that lasted for about a week.
She did not see any embryo expelled.
A month later, her menstrual cycle arrived as expected, but it only lasted 2 to 3 days with minimal discharge, which was also thick and coffee-colored.
Now, more than a month has passed, and her menstrual cycle has not come, and she has tested negative for pregnancy.
What could be the issue?

Ryo, 20~29 year old female. Ask Date: 2004/10/26

Dr. Dai Qihan reply Obstetrics and Gynecology


Hello: Your question must take into account whether an abdominal ultrasound was performed to confirm your girlfriend's gestational age.
The amount of bleeding can be influenced by the gestational age.
It is recommended that you return to the original hospital for a follow-up examination.

After taking RU486, it's common for individuals to experience a range of symptoms and changes in their menstrual cycle. RU486, also known as mifepristone, is a medication used to terminate early pregnancies. It works by blocking the hormone progesterone, which is necessary for maintaining a pregnancy. Following the administration of RU486, many women report experiencing bleeding, cramping, and other symptoms as their body begins to expel the pregnancy tissue.

In your case, your girlfriend has experienced only light, brownish discharge for about a week after taking RU486, followed by a menstrual cycle that was shorter and lighter than usual. This can be concerning, especially since she has not seen any significant bleeding or passed any tissue. It’s important to understand that the experience of bleeding after taking RU486 can vary significantly from person to person. Some women may have heavy bleeding, while others may have very light bleeding or spotting.

The brownish discharge you described is often old blood, which can occur as the body begins to clear out the uterine lining. The fact that she had a menstrual period a month later, albeit lighter and shorter, could indicate that her body is still adjusting to the hormonal changes following the abortion. It is not uncommon for menstrual cycles to be irregular for a few months after an abortion, whether it was medical or surgical.
However, the absence of menstruation in the following month, along with a negative pregnancy test, raises some questions. It is possible that her body is still recovering from the hormonal changes, which can lead to irregular cycles. Stress, changes in weight, and other factors can also impact menstrual regularity.
Here are some considerations and recommendations:
1. Follow-Up Appointment: It is crucial for your girlfriend to schedule a follow-up appointment with her healthcare provider. This is important to ensure that the abortion was complete and that there are no complications, such as retained tissue, which could lead to further issues.

2. Monitoring Symptoms: Keep an eye on any additional symptoms that may arise, such as severe pain, fever, or foul-smelling discharge, which could indicate an infection or other complications.

3. Understanding Menstrual Irregularities: After an abortion, it can take some time for the menstrual cycle to return to its normal pattern. It’s not unusual for cycles to be lighter, shorter, or irregular for a few months.

4. Lifestyle Factors: Encourage your girlfriend to maintain a healthy lifestyle, including a balanced diet, regular exercise, and stress management techniques, as these can all influence menstrual health.

5. Pregnancy Testing: If her period does not return in the next month or if she has any concerns, she should take another pregnancy test or consult her healthcare provider for further evaluation.

6. Emotional Support: The emotional and psychological impact of an abortion can also affect menstrual cycles. Ensure that she has access to emotional support, whether through friends, family, or professional counseling.

In summary, while the symptoms your girlfriend is experiencing can be concerning, they are not uncommon after taking RU486. However, it is essential to follow up with a healthcare provider to rule out any complications and to discuss any ongoing concerns regarding her menstrual cycle.
