Is it normal to have bleeding after medical abortion without seeing the fetal sac?

If bleeding continues after medical abortion and the fetal sac is not visible, it is likely caused by incomplete abortion. In this case, the patient needs to go to the hospital again for a uterine curettage. In addition to the symptoms of bleeding caused by incomplete abortion, medical abortion may also cause adverse reactions such as gastrointestinal reactions and allergic reactions. The following is a detailed introduction to the adverse reactions of medical abortion.

1. Vaginal bleeding

It is normal for vaginal bleeding after medical abortion to last within two weeks and the amount of bleeding does not exceed the normal menstrual volume. If the bleeding lasts for more than two weeks and the amount of bleeding is greater than the normal menstrual volume, the cause of bleeding should be identified as much as possible and a uterine curettage should be considered.

2. Gastrointestinal reactions

This is a common adverse reaction of mifepristone. Symptoms include nausea, vomiting, abdominal pain, diarrhea, and often mild to moderate fever after taking the medicine. Regarding this reaction, mild cases can be left for observation and no special treatment is required. Severe cases should be treated actively with symptoms on the basis of bed rest. For example, if nausea and vomiting are severe, vitamin B1 and B6 should be injected intramuscularly or intravenously. For patients with significant abdominal pain, belladonna or atropine should be taken orally, and for patients with fever, physical cooling should be applied.

3. Symptoms of vagus nerve excitement

Some women may experience symptoms of vagus nerve excitement such as irritability, pale complexion, profuse sweating, chest tightness, palpitations, bradycardia, etc. within minutes after taking the medicine.

4. Incomplete abortion

The success rate of terminating early pregnancy by combining mifepristone and misoprostol can reach 98%-99%, and the failure rate is less than 2%. The main reason for failure is incomplete abortion, that is, part of the embryonic tissue is retained in the uterine cavity. The clinical manifestations are irregular lower abdominal pain and persistent bleeding after abortion.

5. Allergic reaction

It is relatively rare. Some women with specific physical conditions may have an allergic reaction after taking mifepristone. Most reactions are mild, with rashes scattered on the limbs and trunk as the main manifestation. Occasionally, anaphylactic shock reactions with a drop in blood pressure may occur.

6. Fatigue

Fatigue and weakness due to the anti-glucocorticoid effect of mifepristone.

Medical abortion is mainly suitable for women who are within 7 weeks of pregnancy to terminate pregnancy. The success rate of medical abortion is actually not high. If you are not careful, incomplete abortion is very likely to occur. Therefore, it is very important for women who are about to have a medical abortion to understand the adverse reactions of medical abortion in advance.
