Can You Get Pregnant After Taking RU486 and Having Unprotected Sex? - Obstetrics and Gynecology

Share to:

The possibility of becoming pregnant after having sexual intercourse following the intake of RU486 (mifepristone) depends on several factors, including the timing of the medication and the stage of pregnancy. RU486 is primarily used for medical abortion, and if taken correctly


Hello Doctor: I started taking abortion medication on October 1st.
On October 4th, I took three pills within an hour and then began experiencing abdominal pain, bleeding, and vomiting.
During my first follow-up appointment on October 7th, the doctor confirmed that the embryo was no longer present.
At my second follow-up on October 14th, the doctor told me that the process was going smoothly.
I had some intermittent bleeding on October 12th and 13th, but it was very minimal.
On October 15th, I had unprotected sexual intercourse with my boyfriend, and he ejaculated inside me.
Is it possible that I could be pregnant? If sexual intercourse occurs during bleeding, is it not possible to become pregnant?

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello:
1.
The ovaries need to have mature eggs in order to conceive.
Generally, after a miscarriage, the ovaries restart and begin producing new eggs, which typically takes about two weeks.
Counting from October 4, this means that after two weeks, around October 18, it is possible to conceive again.
Therefore, the likelihood of becoming pregnant from intercourse on October 15 is low, unless you are among the few individuals who ovulate particularly quickly.
2.
Is it true that if intercourse occurs during bleeding, pregnancy cannot happen? It is still possible.
Moreover, engaging in sexual activity during this time may increase the risk of inflammation.
If intercourse does occur, it is advisable to use condoms, both for contraception and to reduce the risk of inflammation.
Wishing you peace and health,
Dr.

After taking RU486 (mifepristone) for a medical abortion, it is indeed possible to become pregnant again if you engage in unprotected sexual intercourse. RU486 is designed to terminate an existing pregnancy, and while it is effective in doing so, it does not provide any form of contraception or prevent future pregnancies.

In your case, you mentioned that you took RU486 on October 1st and experienced bleeding and other symptoms typical of a medical abortion. By October 15th, you had unprotected sex with your boyfriend. Since the abortion process can take several days, and you were still experiencing some bleeding, it is important to understand that ovulation can occur relatively soon after an abortion. This means that if you had unprotected sex during your fertile window, there is a possibility of becoming pregnant again.

To clarify, bleeding after taking RU486 does not guarantee that you cannot conceive. The bleeding is a result of the abortion process, and while it may indicate that the pregnancy has ended, it does not prevent ovulation from occurring. Ovulation typically happens about two weeks before your next menstrual period, and if you have unprotected sex during this time, sperm can fertilize an egg, leading to a new pregnancy.

If you are concerned about the possibility of becoming pregnant again, it is advisable to take a pregnancy test if your next period is late. Additionally, if you wish to avoid future pregnancies, consider discussing contraceptive options with your healthcare provider. There are various methods available, including hormonal birth control, intrauterine devices (IUDs), and barrier methods, which can help prevent unintended pregnancies.

In summary, yes, it is possible to get pregnant after taking RU486 and having unprotected sex. If you have any concerns about your reproductive health or potential pregnancy, it is best to consult with a healthcare professional who can provide personalized advice and support.
