Ultrasound is usually done around 40 days of pregnancy to find out the pregnancy. This is because the gestational sac can enter the uterine cavity only around 40 days of pregnancy, and through ultrasound, ectopic pregnancy, etc. can be ruled out. However, if you want to know the pregnancy as early as possible, it is recommended to draw blood to check the HCG in blood, and you can also use early pregnancy test paper to check. After pregnancy is confirmed, it is better to pay attention to rest and strengthen diet and nutrition in order to promote the development of the baby; do not contact with things that have radiation, do not take drugs indiscriminately, and do not smoke or drink alcohol, which can easily cause fetal malformation and other symptoms; it is better to have regular maternity checkups, through ultrasound, Down’s syndrome screening, and if necessary, amniocentesis, etc., which can determine the development of the baby, and if the fetus develops abnormally, it is better to abort or If the fetus develops abnormally, it is better to abort or induce labor in time.
