Pregnancy

Pregnancy

Pregnancy is roughly 40 weeks of growth for both mother and baby. Regular checkups, folic acid, and avoiding harmful things are the foundation.

Updated 2026-10

Key checklist for this stage

  • After a positive test, see an obstetrician for a first visit and confirm your due date.
  • In Korea, register as a pregnant woman at your local public health center. Support such as folic acid and iron supplements varies by area.
  • Get a pregnancy confirmation from your clinic and apply for the pregnancy and childbirth medical expense voucher on the National Happiness Card.
  • Take folic acid from before conception through early pregnancy.
  • Stop alcohol and smoking completely, and avoid secondhand smoke.
  • Tell your doctor or pharmacist about any medicines, herbal remedies, or supplements you take.
  • If you work, look into workplace protections during pregnancy and plan maternity and parental leave.

Prenatal checkups

Prenatal checkups track the health of mother and baby and catch problems early. Typically visits are every 4 weeks until mid-pregnancy, every 2 weeks later on, and weekly near the due date. Exact intervals and tests depend on your clinic and situation.

Main tests include early blood and urine tests and ultrasound, first-trimester screening for fetal anomalies, a detailed mid-pregnancy ultrasound, gestational diabetes screening, and checks on the baby near term. Screening tests estimate risk rather than give a diagnosis, so ask your care team what each result means.

Blood pressure, weight, and urine are checked at each visit. Rising blood pressure or protein in the urine can point to preeclampsia and calls for closer monitoring.

TIPKeep a running list of questions on your phone and ask them all at your next visit.

Folic acid and nutrition

Folic acid lowers the risk of neural tube defects. The neural tube forms very early, often before you know you are pregnant, so it is best to start when you are planning a pregnancy. The US CDC recommends 400 micrograms of folic acid daily for women who could become pregnant. If a previous pregnancy had a neural tube defect or you take certain medicines, you may need more, so talk with your doctor.

Iron needs rise from mid-pregnancy. When to start iron and how much should be decided with your doctor based on blood tests. You do not need to eat for two; a varied diet of vegetables, fruit, protein, and dairy is what matters. With morning sickness, eat small amounts often and drink enough fluids.

What to avoid

  • Alcohol: no safe amount during pregnancy is known. Avoid it throughout pregnancy.
  • Cigarettes and e-cigarettes: they raise the risk of preterm birth and low birth weight. Avoid secondhand smoke too.
  • Raw or undercooked foods: raw beef, undercooked meat and eggs, and raw shellfish such as oysters carry risks of food poisoning, listeria, and toxoplasma. Cook them thoroughly.
  • Avoid unpasteurized milk and cheese and chilled ready-to-eat food that has been kept a long time.
  • Avoid large fish that may be high in mercury (such as shark and swordfish); eat other fish cooked and in moderation.
  • Cut back on caffeine. It is in green tea, energy drinks, and chocolate as well as coffee.
  • Do not take medicines, herbal remedies, or supplements on your own. Ask a doctor or pharmacist even about cold medicine.
  • Wear gloves or let someone else handle cat litter and gardening soil.
  • Do not stay long in saunas or hot rooms that raise your body temperature a lot.
TIPIf you drank alcohol or took medicine before you knew, tell your care team honestly at the next visit rather than blaming yourself.

Go to the hospital right away if

  • You have vaginal bleeding (call even if it is light)
  • You have severe or cramping abdominal pain
  • Fluid that may be amniotic fluid is leaking
  • You have regular tightening or pain before 37 weeks
  • The baby's movements are clearly fewer than usual or you cannot feel them
  • You have a severe headache, blurred or flashing vision, or sudden swelling of the face or hands
  • You have a fever of 38ยฐC or higher, or keep vomiting and cannot keep water down
TIPSave your clinic's night and weekend contact number in advance.
SEE A DOCTOR IFCall 119 (Korea's emergency number) right away for shortness of breath, chest pain, confusion, seizures, or heavy bleeding.

Pregnancy support in Korea

In Korea, once pregnancy is confirmed, people covered by National Health Insurance (including dependents) can receive a pregnancy and childbirth medical expense voucher on the National Happiness Card. It can be used for prenatal checkups and childbirth-related care, and multiple pregnancies receive more. After getting a pregnancy confirmation from your clinic, apply through a card company, the National Health Insurance Service, or online.

Registering at a public health center gives access to folic acid and iron supplements, prenatal tests, and childbirth classes, depending on the area. After birth, programs such as the First Meeting Voucher, the Parent Allowance, and the Child Allowance follow.

  • Workplace protections such as reduced working hours during pregnancy and time off for prenatal checkups
  • Medical expense support for high-risk pregnancies (with eligible conditions and income criteria)
  • Local government support such as transport or postpartum care support for pregnant women
TIPAmounts and eligibility change every year, so check the latest rules on Bokjiro, Government24, or the National Health Insurance Service.

Getting ready and caring for yourself

Mood swings during pregnancy are common. But if you feel depressed or anxious for more than two weeks and it affects sleep, eating, or daily life, it may be prenatal depression, so mention it at your checkup. You do not have to cope alone.

  • Check the route and travel time to your birth hospital, including the night entrance.
  • Install an infant car seat in advance. You need it from the day you leave the hospital.
  • Prepare a firm, flat mattress for the baby without soft blankets or pillows.
  • Talk with your partner about the timing of leave and how to share housework.

FAQ

When should I start and stop folic acid?

The general advice is to take it from when you start planning a pregnancy (ideally at least a month before) through early pregnancy. Whether to continue after that or switch to iron is something to discuss with your doctor.

Can I drink coffee while pregnant?

It is best to cut back on caffeine. Daily limits differ slightly between organizations, so tell your care team how much you usually drink and decide together. Count caffeine from green tea, energy drinks, and chocolate too.

How do I apply for the pregnancy medical expense support in Korea?

Get a pregnancy confirmation from your clinic and apply for the National Happiness Card through a card company, the National Health Insurance Service, or online. Amounts and the period of use can change each year, so check the latest rules on Bokjiro or the National Health Insurance Service.

The baby seems to be moving less. Can I wait?

Lie on your side and focus on the movements. If they are clearly fewer than usual or you cannot feel them, contact the hospital right away instead of waiting.

Can I take medicine for a cold during pregnancy?

Do not decide on your own. Tell your obstetrician or pharmacist how many weeks pregnant you are and ask. Get checked if you have a fever of 38ยฐC or higher or are short of breath.
