More Info


After taking RU486 (mifepristone) for a medical abortion, it is common for women to wonder when their menstrual cycle will return to normal. Based on the information provided, you took RU486 on August 28, and an ultrasound confirmed that the abortion was complete. Generally, it can take some time for your menstrual cycle to resume after an abortion, and several factors can influence this timeline.

Typically, after a medical abortion, menstruation may return within four to six weeks. In your case, since you took RU486 on August 28, you can expect your next period to arrive around late September to early October. It is important to note that individual experiences may vary. Some women may find that their periods return sooner, while others may experience a delay. Factors such as hormonal fluctuations, stress, and individual health conditions can all play a role in the timing of your next menstrual cycle.

After a medical abortion, it is also common to experience some irregular bleeding or spotting for a few weeks. This bleeding is usually lighter than a normal period and can vary in duration. If you find that the bleeding persists for an extended period or becomes excessively heavy, it is advisable to consult your healthcare provider.

It's also worth mentioning that after a medical abortion, ovulation can occur as early as two weeks post-abortion. This means that it is possible to become pregnant again before your next period arrives. If you are not planning to conceive again, it is essential to discuss contraceptive options with your healthcare provider.

In summary, while you can generally expect your period to return within four to six weeks after taking RU486, individual experiences may vary. If you have any concerns about your menstrual cycle or experience any unusual symptoms, it is always best to reach out to your healthcare provider for personalized advice and support. They can provide you with the most accurate information based on your specific situation and health history.
