What is the Optimal Time to Take Abortion Pills? Are There Significant Risks Involved?

In cases of unplanned pregnancy where the child cannot be retained due to various reasons, many individuals choose surgical abortion as a solution. Generally, abortions are suitable when the pregnancy duration does not exceed 49 days and the gestational sac is less than 8MM in size during medical examination. Currently, there are two types of abortions: medical abortion and painless abortion. Medical abortion involves the use of abortion drugs, which is a relatively simple and convenient method with minimal harm to women's physical health.

1.1 If a pregnant woman takes abortion drugs within the optimal time frame, it can increase the success rate of abortion. Many women believe that medical abortion only requires taking medication, sometimes neglecting the optimal timing for the procedure. Failing to undergo medical abortion within the optimal time frame can affect its effectiveness, sometimes leading to the need for a second abortion. Medical abortion is suitable for pregnancies within 49 days, with the average diameter of the gestational sac measured by B-ultrasound being less than 2.3 centimeters.

1.2 The optimal time for taking abortion drugs is within 49 days after pregnancy, but not exceeding 90 days. Once the pregnancy duration exceeds 90 days, the fetus will have developed significantly, rendering medical abortion impractical, and surgical abortion or induction of labor may be necessary. Additionally, the calculation of pregnancy duration is not based on the timing of sexual intercourse.

1.3 The best time to take abortion drugs is within 10 weeks of gestation, as the fetus is still in its early stages of development, and the uterine tissue is relatively simple. This ensures the safety of medical abortion and faster recovery after taking the drugs. Women considering abortion should also decide which type of abortion procedure they prefer.

1.4 The use of abortion drugs is recommended for women within 49 days of amenorrhea, preferably under 34 years of age.

1.5 Before taking abortion drugs, a pregnant woman should undergo a B-ultrasound examination to confirm that the pregnancy is intrauterine and consider medical abortion accordingly.

2.1 Infection: After taking anti-pregnancy drugs, sometimes the pregnancy tissue may not be completely expelled, leading to incomplete uterine lining recovery and prolonged vaginal bleeding. This can allow bacteria to enter the uterus from the vagina, causing endometritis.

2.2 Incomplete Abortion: Some women may experience incomplete abortion after taking the drugs, affecting uterine contraction and endometrial repair. This can result in significantly increased vaginal bleeding, sometimes exceeding two to three times the normal menstrual flow. In severe cases, it can lead to hemorrhage, anemia, and shock, requiring blood transfusion and emergency surgical curettage to stop the bleeding.

2.3 Impact on Future Fertility: Medical abortion can affect future pregnancies, potentially leading to habitual abortion or even infertility.

2.4 Menstrual Irregularities: Anti-pregnancy drugs can suppress ovarian function, affecting follicle growth, development, and ovulation. This can lead to menstrual irregularities, manifesting as shortened or prolonged menstrual cycles and increased menstrual flow.
