After being pregnant for 12 weeks, what tests need to be done?

Patient's question:

[Had a B examination once, want to get what help: Ask the doctor: At 12 weeks of pregnancy, what needs to be checked? 3D and 4D what time to check? When to do the antenatal manual? Is it after the examination that you know what nutrients need to be supplemented? Thank you!]

Doctor's answer:

Pregnancy Week 12 Check-up Requirements:
1. Height and Weight: Changes in weight can indicate fetal development status. Abnormal weight gain may suggest gestational hypertension syndrome.
2. Blood Pressure: Normal blood pressure should not exceed 130/190 mmHg. Elevated blood pressure may indicate gestational hypertension syndrome.
3. Fundal Height and Abdominal Circumference: To assess fetal development.
4. Fetal Heart Rate: The fetal heartbeat can now be heard. A heartbeat confirms the baby is alive, with a normal range of 120–160 beats per minute.
5. Gynecological Internal Examination: Primarily to check the size and position of the uterus.
6. External Pelvic Measurement: To evaluate the birth canal and determine the basis for delivery methods.
7. Breast Examination: To assess breast development, which helps correct issues like inverted nipples before birth.
