Menstrual issues


On June 13, I took the first dose of RU486, and during my follow-up appointment on June 26, the doctor confirmed that everything was cleared.
My first menstrual period after the miscarriage was on July 17.
When can I expect my period in August? I had sexual intercourse in between without using a condom, but there was no ejaculation inside.

Hello, it should be around mid-August.
It is best to take contraceptive measures.
If your period is more than a week late, it is recommended to see a gynecologist.
Wishing you good health.

More Info


After an abortion, particularly a medical abortion using RU486 (mifepristone), it is common for women to experience changes in their menstrual cycle. Understanding what to expect can help alleviate anxiety and prepare for the upcoming changes.

Typically, after a medical abortion, it may take some time for your menstrual cycle to return to its regular pattern. The first period after an abortion can vary significantly in timing, flow, and symptoms. Generally, most women will have their first menstrual period within 4 to 6 weeks after the abortion. In your case, since you had your abortion on June 26 and are inquiring about your period in August, it is reasonable to expect your next period to arrive sometime between late July and early August, depending on your individual cycle.

Several factors can influence the timing of your first post-abortion period:
1. Hormonal Changes: After an abortion, your body needs time to readjust hormonally. The levels of hormones such as estrogen and progesterone will fluctuate as your body returns to its pre-pregnancy state. This hormonal adjustment can affect the timing and characteristics of your menstrual cycle.

2. Cycle Regularity: If you had a regular menstrual cycle before the abortion, your periods may return to a similar pattern. However, if your cycles were irregular, it might take longer for your body to establish a new rhythm.

3. Physical Recovery: The physical recovery process after an abortion can also impact your menstrual cycle. Factors such as stress, emotional well-being, and overall health can play a role in how quickly your cycle normalizes.

4. Sexual Activity: Engaging in sexual activity after an abortion, even if protection was used, can also influence your menstrual cycle. If you had unprotected intercourse, there is a possibility of pregnancy, which could delay your period. If you are concerned about the possibility of being pregnant again, it may be wise to take a home pregnancy test if your period does not arrive as expected.

5. Consultation with Healthcare Provider: If you have concerns about your menstrual cycle or experience any unusual symptoms, such as heavy bleeding, severe pain, or signs of infection (such as fever or foul-smelling discharge), it is crucial to consult with your healthcare provider. They can provide personalized advice and ensure that your recovery is progressing well.

In summary, while it is common for your first period after an abortion to be irregular or delayed, most women can expect their menstrual cycle to return within a few weeks. If you have any concerns about your cycle or potential pregnancy, do not hesitate to reach out to your healthcare provider for guidance and support.
