There are many items that need to be checked during pregnancy, and they are different for each period. They are probably: blood routine, liver and kidney function, coagulation, syphilis, HIV, hepatitis B, urine routine, progesterone, thyroid function test, Down’s syndrome screening, glucose tolerance test, and blood pressure. Ultrasound, 4D examination, fetal heartbeat, fetal heart monitoring, and amniocentesis or non-invasive DNA test may be needed for some pregnant women at any time during pregnancy. Relevant examinations should be perfected in time to avoid any unexpected situation. Pregnant women also need to pay attention to self-observation of fetal movement and the presence of abdominal pain, bloating, vaginal bleeding, vaginal fluid and other conditions. Pay attention to more rest during pregnancy and avoid staying up late and straining.
