The card is usually issued around 6-8 weeks of pregnancy. There is no way to determine whether the pregnancy is intrauterine or ectopic in the first 6 months of pregnancy. Usually an ultrasound is done after 6 weeks to check if the pregnancy is intrauterine or ectopic, or if the pregnancy is viable, and the card will be issued after the pregnancy is confirmed to be viable. The possibility of miscarriage is higher in the first 3 months of pregnancy, so it is important to take more rest and avoid straining, and if you have abdominal pain or vaginal bleeding, you should go to the hospital in time for examination. You should take folic acid in the first 3 months, and go to the hospital for NT examination at 11-13+6 weeks of pregnancy to check the thickness of the nuchal translucency layer of the fetus and to initially check whether the fetus has any malformation. After that, you should go to the hospital every 4 weeks until the 37th week of pregnancy, and after the 37th week of pregnancy, you should go to the hospital once a week for a maternity check-up.
