There is no scientific basis for the statement when is the best time to go for a checkup in early pregnancy. Generally, you need to go to the hospital around 40 days after menopause for a checkup to confirm pregnancy. Usually about 10 days after the last intercourse, you need to go to the hospital to check the blood human chorionic gonadotropin or urine human chorionic gonadotropin under the doctor’s advice, to determine whether you are pregnant or not. If you are sure that you are pregnant, go to the hospital around 40 days after menopause for an ultrasound to determine if the pregnancy is intrauterine. The doctor will determine if blood tests and other tests are needed. Then, when the pregnancy is between 50 and 60 days, another ultrasound examination is needed to determine whether there are fetal buds, the size of the embryo, etc., and the development of the embryo. In the early stage of pregnancy, pregnant women need to avoid strenuous exercise, maintain a light diet, take folic acid supplements under the guidance of a professional doctor, and follow the doctor’s instructions for regular checkups.
