If you are pregnant, how long does it take to go to the hospital for a check-up?

Patient's question:

If you are pregnant, how long does it take to go to the hospital for a check-up?

Doctor's answer:

Do you want to check if it's early pregnancy? If so, it takes about 1 month. 5—6 weeks
　　Through ultrasound examination, the position of the gestational sac in the uterus can be roughly seen. If it is still not visible, it is necessary to suspect the possibility of ectopic pregnancy. If the pregnant woman does not have vaginal bleeding, it is only necessary to check the implantation site of the gestational sac. If there is vaginal bleeding, it is usually "threatened miscarriage." During this period, if some tissue falls out of the vagina, it is necessary to consider whether it is really a miscarriage. Additionally, between weeks 5—8 of pregnancy, the number of embryos can be seen to determine if the expectant mother is carrying twins!
　　6—8 weeks
　　Visible fetal heartbeat, yolk sac
　　During an ultrasound examination between weeks 6—8 of pregnancy, the embryonic tissue inside the gestational sac can be seen. If the fetal heartbeat is visible, it indicates that the fetus is currently in a normal state. Additionally, under ultrasound scanning, the yolk sac, which supplies nutrients to the fetus before week 12, can also be seen. This is the fetus's own "snack box"! If the fetal heartbeat is not visible, the expectant mother can wait for a few days or a week before returning to the hospital for another ultrasound examination.
