Patient's question:
Here is the English translation of the provided text:"I used a pregnancy test kit and it showed a strong positive result. Is it possible that I'm pregnant? How many weeks pregnant can I get an ultrasound scan?"
Doctor's answer:
As long as there is sexual intercourse without contraception, pregnancy is possible. If your period does not arrive within 10 days or more, it is recommended to use a pregnancy test strip or check blood HCG for confirmation. Generally, 3-5 ultrasound examinations are performed during pregnancy, with one in the early stages to confirm pregnancy, estimate embryonic development, and diagnose common early pregnancy conditions such as ectopic pregnancy, molar pregnancy, and various types of miscarriage. In the second trimester (weeks 22-26), a 4D color Doppler ultrasound is conducted for structural screening to check for major fetal abnormalities and abnormalities in major organs. In the third trimester, the fetus, amniotic fluid, and placenta are examined.
