Pregnancy questions, answered

The Indian government's Pradhan Mantri Surakshit Matritva Abhiyan recommends a minimum of 4 antenatal visits — in the first trimester, at 14–26 weeks, at 28–34 weeks, and at 36 weeks onwards. However, for high-risk pregnancies (gestational diabetes, hypertension, twin pregnancies, or prior complications), fortnightly or even monthly visits are standard clinical practice. If your pregnancy is high-risk, always follow your obstetrician's schedule rather than the minimum.

TIFA stands for Targeted Imaging for Fetal Anomalies. It is a detailed anatomy ultrasound performed between 18–22 weeks of pregnancy. The scan evaluates fetal organ development — the heart, brain, spine, kidneys, limbs, and facial structures. This window is optimal for detection of major structural anomalies. Missing this window significantly limits the ability to identify and counsel about certain conditions. If you missed it, discuss with your doctor whether a detailed cardiac scan or fetal echocardiography is appropriate.

Seek immediate care for: vaginal bleeding at any stage of pregnancy; severe headache especially with visual disturbance (blurring, flashing lights, or loss of vision); sudden or severe swelling of face, hands, or feet; decreased or absent fetal movements after 28 weeks; leaking of fluid from the vagina before 37 weeks; severe abdominal or lower back pain; high fever with or without chills; or difficulty breathing. These can indicate placenta previa, pre-eclampsia, PPROM, abruption, or other emergencies requiring urgent evaluation.

Gestational diabetes mellitus (GDM) is high blood sugar first detected during pregnancy. In India, it is screened using a 75g oral glucose tolerance test (OGTT) at 24–28 weeks. For high-risk women (family history of diabetes, prior GDM, PCOS, or high BMI), screening is done earlier. Management starts with a diabetic diet — reducing refined carbohydrates, increasing fibre, eating 5–6 small meals per day, and eliminating sugar-sweetened drinks. If diet alone fails to control blood sugars, insulin therapy is started. Poorly controlled GDM increases risk of macrosomia (large baby), shoulder dystocia, NICU admission, and gestational hypertension.

The normal AFI is 8–18 cm between 28–36 weeks of pregnancy. A value below 5 cm is oligohydramnios (low fluid), which may indicate fetal kidney problems, post-date pregnancy, or placental insufficiency. A value above 25 cm is polyhydramnios (excess fluid), associated with fetal swallowing disorders, GDM, or structural anomalies. If your scan reports low or high AFI, do not panic — a single measurement is interpreted along with fetal wellbeing, Doppler studies, and clinical context. Discuss the finding with your obstetrician before drawing conclusions.

Light spotting in the first trimester can be implantation bleeding (normal) or related to a sensitive cervix. However, any bleeding in pregnancy must be evaluated. Red flags requiring immediate attention: heavy bleeding (soaking a pad), cramping along with bleeding, passage of tissue, or bleeding after 12 weeks. A transvaginal ultrasound will be done to check for subchorionic haematoma, threatened abortion, or ectopic pregnancy. Do not assume first trimester spotting is normal without a scan and clinical evaluation.

Avoid: raw or undercooked meat and eggs; unpasteurised dairy and soft cheeses; raw sprouts; large fish high in mercury (shark, swordfish, king mackerel); unwashed raw fruits and vegetables; papaya (particularly raw or semi-ripe); pineapple in large amounts; excessive vitamin A (liver, certain supplements); alcohol entirely; and excess caffeine (keep below 200mg per day — roughly one cup of coffee). Street food prepared in unhygienic conditions carries risk of listeria and salmonella. Moderate spice in home-cooked food is generally safe.

Folic acid should ideally be started at least one month before conception and continued through the first trimester (12 weeks). The standard dose is 400–500 mcg per day for low-risk pregnancies. For women with a prior neural tube defect pregnancy, epilepsy on sodium valproate or carbamazepine, or diabetes, the recommended dose is 5 mg per day — this requires a prescription. Folic acid prevents neural tube defects like spina bifida, which form within the first 28 days of pregnancy — often before a woman knows she is pregnant.

A routine antenatal (dating) scan at 8–12 weeks confirms gestational age and viability. The anatomy (TIFA) scan at 18–22 weeks evaluates fetal structure. A growth scan (done from 28 weeks onwards) measures fetal weight, head circumference, abdominal circumference, and femur length to track growth, and checks the amniotic fluid and placenta. Doppler studies (umbilical artery Doppler) assess blood flow between the placenta and baby — used in high-risk or growth-restricted pregnancies. Your obstetrician will prescribe scans based on your specific clinical picture.

Air travel is generally safe up to 36 weeks for uncomplicated singleton pregnancies. Most airlines restrict travel after 32–36 weeks. Risks include deep vein thrombosis (DVT) from prolonged sitting — wear compression stockings, stay hydrated, and walk the aisle every hour. Avoid travel if you have a high-risk pregnancy (placenta previa, pre-eclampsia, PPROM, or multiple gestation). For travel after 28 weeks, carry a letter from your obstetrician. Consult your doctor before booking any long-haul flight.

Recommended weight gain depends on your pre-pregnancy BMI. For underweight women (BMI < 18.5): 12.5–18 kg. For normal weight (BMI 18.5–24.9): 11.5–16 kg. For overweight (BMI 25–29.9): 7–11.5 kg. For obese (BMI ≥ 30): 5–9 kg. Weight gain should be gradual — about 1–2 kg in the first trimester, then 0.4–0.5 kg per week in the second and third trimesters. Insufficient gain is linked to fetal growth restriction; excessive gain increases GDM and hypertension risk.
