Positive Urine Test Early Pregnancy

When a home urine pregnancy test comes up with two lines, joy comes together with a sense of being at a loss, "now where do I start." In the clinic, what mothers ask most often right after confirming pregnancy is about weight, supplements, caffeine, and the testing schedule. Wooahan Women's Clinic does not perform deliveries directly, but together with the deputy director, it looks after early-pregnancy mothers with prenatal care that conforms to the Samsung Seoul system. In this article, I will organize, step by step, the big picture of the tests and lifestyle management you will receive in early pregnancy.

If you have confirmed a positive urine pregnancy test, the next step is a first visit to the OB-GYN. The American College of Obstetricians and Gynecologists (ACOG, 2024) recommends receiving the first prenatal examination in early pregnancy, ideally before 10 weeks of pregnancy. In this period, the estimated due date is determined, whether the mother and fetus fall into a high-risk group is identified, and problems that may arise going forward are foreseen in advance to reduce risk factors.

The most important thing at the first visit is honest history-taking. The more you tell us, without adding or subtracting, your past pregnancy/miscarriage history, medications being taken, family history, and underlying conditions, the more the accuracy of management rises. In the clinic, we often see cases where information you skipped over thinking "this much surely doesn't need to be mentioned" turns out to be an important clue.

At the first visit, basic prenatal blood tests are conducted. ACOG (2024) recommends conducting a complete blood count, blood type and Rh factor, antibody screening, rubella antibody, syphilis serology test, and hepatitis B test as a standard panel for new mothers. If you are at the stage of preparing for pregnancy, there are tests good to take in advance, so please also refer together to what tests should I get before pregnancy.

Prenatal examinations do not end with one visit but continue on a set schedule according to gestational week. Traditionally, the standard has been visits at 4-week intervals until 28 weeks of pregnancy, 2-week intervals from 28 to 36 weeks, and weekly visits after 36 weeks.

However, this schedule may differ depending on the mother's age, underlying conditions, and the presence of complications during pregnancy. ACOG (2025) newly recommended tailored prenatal care that, for low-risk mothers, adjusts the number of in-person visits to suit individual circumstances and utilizes various methods such as telemedicine. In other words, it is a direction of designing the schedule by considering medical and social conditions and the mother's preference together, rather than uniformly applying the same number to all mothers.

In mid-pregnancy, fetal anomaly screening and detailed ultrasound follow. If you are curious about the flow of tests in this period, looking together at the article organizing when prenatal anomaly screening and amniocentesis are done is helpful.

What early-pregnancy mothers, especially those pregnant with their first, worry about most is weight. When you become pregnant, there are many things you want to eat and the amount tends to increase, so many feel anxious about whether gaining weight is okay and whether gestational diabetes might develop.

To say the conclusion first, as long as you do not greatly exceed the limit, you may comfortably eat what you want to eat. However, there is a textbook-recommended range of weight gain. ACOG (2024) guides the appropriate amount of gain according to pre-pregnancy body mass index (BMI) as follows.

The reason weight management is needed is clear. Excessive weight gain is reported to be associated with the risk of various complications such as gestational hypertension, preeclampsia, gestational diabetes, macrosomia, and cesarean delivery. Conversely, if weight gain is too small, a low-birth-weight baby may result. For reference, twin pregnancy has different criteria, so please be consulted separately.

Nutritional supplementation during pregnancy is not "the more the better" but "within the recommended range" as a principle. Excessive supplements can rather become poison.

The most central is folic acid. ACOG (2024) recommends an intake of 600 micrograms of folic acid a day during pregnancy, and folic acid is a form with confirmed neural-tube-defect prevention effect. It is good to begin taking 400-800 micrograms a day in advance from the pregnancy-preparation stage, and to supplement iron together after pregnancy.

Calories do not need to be increased as much as you might think. During pregnancy, an additional intake of only about 100-300 kcal a day is recommended. For protein, taking about 1g per 1kg of body weight in early pregnancy, and increasing it further toward late pregnancy, is helpful.

• Folic acid: 600mcg a day (from 400-800mcg in the preparation stage)
• Iron: start supplementing after confirming pregnancy
• Additional calories: at the level of 100-300 kcal a day
• Do not exceed the recommended amount of supplements

If you want to check overall health items before and after pregnancy at once, using lifecycle screening is also a method.

Exercise is possible during most of pregnancy and is in fact recommended. However, it is good to avoid strenuous exercise to the point of exhaustion, exercise lying down for a long time, exercise that needs a lot of balance and has a high risk of falling, and exercise in a too-cold or too-hot environment. When there is bleeding, abdominal pain or a heavy feeling, or unusual fatigue, you must stop exercising immediately.

Among foods, we are especially careful of two things. The first is mercury. ACOG (2024) recommends avoiding fish species with high mercury content such as shark, swordfish, tilefish, and king mackerel, and limiting canned white tuna (albacore) to within a certain amount per week.

The second is caffeine. ACOG (2024) recommends limiting caffeine during pregnancy to under 200mg a day (about one 12-ounce cup of coffee). The problem is that caffeine is not only in coffee. Caffeine is also in soft drinks such as cola, black tea, green tea, and iced tea, chocolate, cocoa, chocolate milk, and chocolate ice cream, so you must add them up and weigh them.

If there is something confusing about diet or the testing schedule in early pregnancy, please feel free to inquire via the get a consultation on early-pregnancy management button.

During pregnancy, there are things to take care of even in trivial parts of daily life. Wear the car seatbelt so that it does not directly press on the uterus and lower abdomen—the shoulder strap across the chest and the lap belt below the belly. Simply put, think of it as making sure the baby is not compressed.

For a healthy mother, intercourse is not harmful. However, since it is contraindicated when there are risk factors such as placenta previa or risk of preterm birth, it is safe to have your condition checked at a visit.

It is good to receive dental treatment in advance before pregnancy if possible. If you are preparing for pregnancy, we recommend regular dental check-ups. Dental treatment during pregnancy is not contraindicated, but it is because tooth and gum disease during pregnancy is reported to be possibly associated with preterm labor.

Vaccination during pregnancy is important management that protects not only the mother but the baby to be born. ACOG (2024) recommends administering the Tdap (tetanus-diphtheria-pertussis) vaccine between 27 and 36 weeks of pregnancy, as early in this window as possible. Doing this helps the antibodies made by the mother be passed to the baby through the placenta, protecting the neonatal period when the baby is vulnerable to whooping cough.

The influenza (flu) vaccine is administered before the epidemic season to protect mother and newborn together. Besides this, ACOG (2024) also guides COVID-19 and RSV vaccines as recommended during pregnancy, so it is good to have a vaccination plan suited to your pregnancy timing and the season checked at a visit. Why the whooping cough vaccination is important for the whole family is covered in more detail in the article the whooping cough vaccine to take before meeting your newborn.

Conceiving a new life is a big change for the mother as well. You will experience various symptoms such as headache, morning sickness, back pain, fatigue, and drowsiness. If the tests and lifestyle management to receive in early pregnancy feel daunting, please apply for a consultation right now and receive guidance suited to your situation. Wooahan Women's Clinic will be with you on that path toward a healthy birth.
