Patient's question:
Medical Description: I have been experiencing amenorrhea for 25 days. A few days ago, I used a pregnancy test and it showed two lines, but yesterday I had some bleeding. The color of the blood was different from my usual menstrual blood—it was slightly darker.History of Treatment and Effect: I just noticed something was wrong and have not yet received any treatment.
Help Needed: What could be the reason for this situation?
Doctor's answer:
Bleeding in the early stages of pregnancy is a pregnancy symptom. The causes are varied: fetal chromosomal abnormalities, hormonal imbalances in the mother, congenital or acquired uterine developmental abnormalities, immune system problems, viral infections, chronic diseases in pregnant women (such as heart disease, kidney disease, and blood disorders), overexertion, excessive stress, too vigorous sexual activity, external force impact, environmental pollution, improper medication, smoking, drinking alcohol, excessive caffeine intake, or consumption of other foods that promote uterine contractions, etc. Before the placenta is fully formed, the implantation of the embryo is not stable, and therefore many factors can cause miscarriage. When miscarriage occurs, the embryo and the uterine wall separate to varying degrees. If the blood vessels on the separation surface rupture, it will cause vaginal bleeding symptoms.
