Introduction
If unprotected intercourse occurs within one month after miscarriage, it may lead to another pregnancy, resulting in a pregnancy test showing one dark and one faint line. Incomplete expulsion of residual tissue can cause HCG levels in the body to decrease slowly, so that 32 days after the miscarriage, HCG has not yet returned to normal levels. Additionally, malignant transformation of embryonic trophoblastic cells into a tumor can also result in a weakly positive pregnancy test.

After a medical abortion, a pregnancy test showing one dark and one faint line 32 days later can be due to either physiological or pathological causes. Pathological causes include incomplete abortion and gestational trophoblastic tumor, both of which require diagnosis and treatment. The specific analysis is as follows:

I. Physiological Causes

The time for resumption of ovulation after medical abortion varies among individuals. If unprotected intercourse occurred within one month after the abortion, leading to another pregnancy, a pregnancy test may show one dark and one faint line. This can be confirmed with a blood HCG test.

II. Pathological Causes

1. Incomplete Abortion

If retained tissue remains in the uterine cavity after a medical abortion and is not completely expelled, HCG levels in the body may decline slowly and remain above normal levels even 32 days post-abortion, resulting in the aforementioned test result. This condition is often accompanied by abdominal pain and vaginal bleeding. Prompt medical attention is recommended, and curettage may be required.

2. Gestational Trophoblastic Tumor

This tumor arises from malignant transformation of placental trophoblastic cells and can also cause a weakly positive result on a pregnancy test. Patients should seek timely medical evaluation and may require chemotherapy or radiotherapy.

One month after a medical abortion, it is advisable to visit a hospital for a follow-up ultrasound to assess uterine recovery. Identifying the underlying cause is essential for appropriate and timely treatment.
