What are the reactions after taking general medication for abortion?

Patient's question:

I would like to ask about the reactions of medication abortion. If I take the medication and don't experience any adverse reactions, such as abdominal pain, does it mean the medication hasn't worked? Or am I not pregnant? Thank you

Doctor's answer:

Hello: Common Causes of Bleeding and Treatment Principles:
1. Uterine Atony: This is primarily due to the well-developed decidua and chorion in women with a higher gestational age, where the contraction strength induced by commonly used prostaglandin drugs (misoprostol) is insufficient to expel all tissues. Therefore, after the fetal sac tissue is expelled, oxytocin (10-20 units) should be administered promptly to strengthen uterine contractions, and a decoction of Shouguanjian (a traditional Chinese medicine preparation) should be taken (1 bag, 2 times daily for 7 days) to reduce post-abortion bleeding and promote uterine recovery.
2. Residual Chorion and Decidua Tissue: If vaginal bleeding persists for more than 3 weeks after medication abortion and tissue residue is found in the cervix, it is necessary to perform uterine aspiration promptly.
3. Infection Issues: Prolonged vaginal bleeding can lead to uterine cavity infection. Meanwhile, uterine cavity infection can exacerbate bleeding and prolong the bleeding duration. Therefore, for patients with prolonged bleeding, appropriate antibiotics should be administered to prevent infection. If infection has already occurred, selecting antibiotics that target both aerobic and anaerobic bacteria in combination yields better efficacy.
4. After medication abortion, adding Shouguanjian, Eymucao, and Shenghuatang (blood-activating and stasis-resolving traditional Chinese medicines) can help strengthen uterine contractions and promote uterine recovery, thereby reducing uterine bleeding.
After medication abortion, normal work can generally be resumed after 2-3 days of rest, but the following basic points should be noted:
Pay attention to adequate rest and avoid excessive workload;
Avoid catching colds or getting a cold;
Eat more nutritious foods to help the body recover quickly;
Maintain cleanliness of the external genitalia, and avoid sexual activity for one month to prevent damage to the uterus.
