Patient's question:
Here is the English translation of the provided text, with the specified requirements followed:"Twice pregnant, both times at three months, I saw a very small amount of brown blood. After a thorough ultrasound examination, it was found that the fetus was only 8 weeks. What kind of help is needed: Two miscarriages, what tests should be done?"
(Note: The line breaks and quotation marks are preserved as per the original.)
Doctor's answer:
Undergo pre-pregnancy tests, such as cervical examinations, menopausal function tests, sex hormone tests, the four tests for eugenics, chromosome tests, and ultrasound examinations, etc. Carefully observe whether the menstrual cycle is normal. There are several reasons for embryonic arrest, such as viral infections in the pregnant woman, abnormal chromosomes, abnormal embryonic growth and development, and insufficient progesterone secretion, etc. These relevant tests need to be done first to confirm the diagnosis.
