Day 119 baby development and maternal changes

A: When a cramp hits, flex the foot and massage the calf. Prevention: supplement calcium and magnesium, drink water, stretch before bed, wear support stockings and avoid standing too long. About half of pregnant women get cramps; if they’re frequent with weakness or numbness, check blood calcium, magnesium and electrolytes at a prenatal visit.

A: Yes. Most first-time mothers clearly feel movement only at 18-22 weeks; mothers who’ve given birth before feel it a little earlier; heavier builds, placenta praevia or an anterior placenta also delay the sensation. The week-20 ultrasound can confirm, so don’t worry about "not feeling anything".

A: Most Doppler fetal monitors pick up a heartbeat after weeks 10-12; at week 17 the heartbeat is strong, about 110-160 beats per minute. A home fetal-heart monitor can be used occasionally but you don’t need to check daily; don’t panic if you can’t hear it (affected by position and amniotic fluid) — rely on prenatal checks for any abnormality.

A: A cumulative gain of about 2.5-5kg by week 17 is common, with about 0.4-0.5kg a week in the second trimester for a standard BMI. Watch the trend — you can use a weight-gain calculator to manage it by BMI — and talk to the doctor if it’s too fast or too slow.

A: The three measurements at 17 weeks are BPD (biparietal diameter) about 37mm, AC (abdominal circumference) about 115mm, and FL (femur length) about 22mm, reflecting head, abdomen and leg development. If the three are in step, growth is good; a single slight deviation isn’t necessarily abnormal — go by the doctor’s overall assessment.

A: Yes; the second trimester is a good window for massage. Choose a therapist with pregnancy-massage qualifications, use the side-lying position (not face-down), avoid direct pressure on the abdomen and the acupoints near the ankles, and avoid deep leg massage (clot risk). It can relieve back pain, reduce oedema and improve sleep.

A: Practise sleeping on your left side to increase uterine-placental blood flow, using a pregnancy pillow; comfort is the priority, brief right-side or flat positions are fine, and avoid lying face-down on the belly.

A: ACOG recommends about 1000mg of calcium daily in the second trimester; magnesium is also important (nuts, whole grains, dark-green vegetables). Give priority to food sources; if prenatal checks show a deficiency or cramps are obvious, add calcium/magnesium on the doctor’s advice rather than in blind large doses.

A: ACOG advises about 150 minutes of moderate-intensity exercise accumulated weekly (walking, prenatal yoga, swimming), split over 5 days at about 30 minutes a day. Avoid intense exercise and pressure on the abdomen; stop and seek care for pain or bleeding.

A: It’s recommended. The CDC and ACOG recommend that pregnant women receive the inactivated flu vaccine: pregnant women are at higher risk of severe flu, the vaccine protects mother and baby, and it is safe at every stage. During flu season (September to April) you can get vaccinated; tell them you’re pregnant.

A: If there’s no placenta praevia, bleeding or cervical insufficiency, gentle sex is fine using positions that don’t press on the belly and with gentle movements. Pause if you feel unwell or the doctor advises against it.

A: Relaxin loosening the ligaments and the increased load on the pelvis make lumbar soreness and pubic-bone pain common. Avoid standing or sitting too long, wear low supportive shoes, sleep on your side with a pregnancy pillow, and do prenatal yoga and pelvic-floor exercises. Severe pain on one side, or with bleeding or fever, needs medical attention.

A: Eat more fiber-rich fruit and vegetables, drink 1.5-2L of water daily, walk after meals, and toilet on a regular schedule. In serious cases consult a doctor for a pregnancy-safe laxative rather than buying a stimulant laxative yourself.

A: Avoid raw or undercooked meat, fish and eggs, high-mercury large fish, unpasteurised dairy, alcohol, caffeine over 200mg/day, and excess liver.

A: Flying is more comfortable in the second trimester; most airlines don’t require a certificate before 32 weeks and need one after 32 weeks (most prohibit flying after 36 weeks). Choose an aisle seat, stay hydrated, and use compression stockings; ask your doctor first if you have bleeding, pain or placenta problems.

A: The anomaly scan is done at weeks 20-24 with tight slots, so book this week to avoid missing the best window.

A: Higher oestrogen increases white discharge; milky-white, clear and odourless is normal. Yellow-green, foul-smelling, itchy discharge or large amounts of watery leakage needs medical attention; wear cotton underwear and don’t douche.

A: Build it up with red meat, liver (≤50g a week) and spinach paired with vitamin C; once diagnosed, the doctor will prescribe an iron supplement, taken apart from calcium tablets and dairy for better absorption.

A: Pigmentation from pregnancy hormones is common; use sun protection (physical first), gentle skincare and adequate sleep, and most of it fades after delivery. If it darkens and spreads quickly, have the doctor look at it during a prenatal visit.

A: Occasional brief tightening is usually a sensitive uterus or ligament tugging and is common if it resolves on its own. If it becomes regular (every 10 minutes), or comes with pain/bleeding/leakage, seek medical attention.
