After the pregnancy, we must pay attention to go to the hospital for examination in time, there are the following kinds of early pregnancy examination: First, we need to conduct routine blood test and routine urine test, through routine blood test can determine whether the pregnant woman is anemic, and monitor the progesterone value and HCG value in the pregnant woman’s body, if the progesterone value in the body is low in early pregnancy, it may affect the growth and development of the fetus, and various problems such as pre-miscarriage may occur. Secondly, ultrasound examination is also needed in early pregnancy, through which you can see whether there is a gestational sac in the uterine cavity, whether there is a yolk sac in the embryo, whether there is a fetal bud and fetal heart, which is an important indicator of whether the fetus is developing normally. If an ultrasound is performed after a period of pregnancy and no gestational sac or yolk sac is found in the uterine cavity, it may be a case of biochemical pregnancy or ectopic pregnancy, and it is recommended to go to the hospital for treatment in time.
