14 Weeks Pregnant

Baby’s Development

Fetus ~8.7-9 cm (lemon), weight ~43 g [1]. Second trimester begins. Facial muscles work: baby can squint, frown, grimace, and make sucking motions. Lanugo (fine, downy hair) covers body — protects skin, regulates temperature, usually shed before birth. Eyebrows and scalp hair growing. Thyroid produces hormones. Liver produces bile. Spleen produces red blood cells. Kidneys produce urine (fetal urine = ~most amniotic fluid by second half of pregnancy). Movement: kicking, stretching, head turning, thumb-sucking. Genitals visible: external clitoris/penis now distinguishable on detailed ultrasound [2].

Pregnancy Symptoms

“Honeymoon trimester” begins. Energy returns, nausea fades (80%+ of people), mood stabilizes, libido often returns. Symptoms persisting/easing: breast tenderness (less), frequent urination (less — uterus higher), heartburn, bloating, constipation. New: round ligament pain (sharp, lower belly, especially with movement), nasal congestion (rhinitis of pregnancy), gum sensitivity, possible skin tags or moles, hair growth. Some feel “quickening” (flutters) — first-time moms usually 18-22 weeks [2].

Body Changes

Uterus ~size of a small cantaloupe, rising into abdomen. Visible “bump” in first pregnancy (or just bloating for athletic builds). Weight gain target: 1-2 lbs/week from now on; ~12 lbs by week 20 typical. Skin: pregnancy glow (increased blood + oil), possible melasma, linea nigra darkening. Breasts: 1 cup size up, areola darker, colostrum may leak [2].

Tips for Week 14

• Resume/modify exercise — most welcome return of energy. ACOG: 150 min/week moderate. Running OK if pre-pregnancy runner; transition to lower-impact (elliptical, swimming, hiking) as belly grows [1].
• Reassess wardrobe — belly band, maternity jeans (Aritzia, Hatch, Old Navy), supportive bra (no underwire if rib pain). Avoid restrictive waistbands.
• Start pelvic floor exercises — Kegels daily, plus cat-cow, bird-dog, gentle core work. Prevents incontinence, eases birth.
• Schedule second-trimester milestones: anatomy scan (18-22 wk), glucose screening (24-28 wk), TDap vaccine (27-36 wk), Rhogam if Rh-negative (28 wk).

Things To Do (Checklist)

• Get maternity wardrobe essentials (1-2 jeans, leggings, 1-2 bras)
• Start pelvic floor + core exercise routine
• Schedule anatomy scan (18-22 weeks)
• Book babymoon trip if planning (14-28 wk window)
• Discuss exercise modifications with OB

Frequently Asked Questions

Q: I felt something — was that the baby? A: Possibly! “Quickening” feels like flutters, gas, bubbles, or popcorn. First-time moms usually 18-22 weeks. Earlier (16-18 wk) in subsequent pregnancies [2].

Q: Is it safe to dye my hair now? A: Yes. Limited absorption, very low risk. Highlights preferred (less scalp contact). No data showing harm [1].

Q: I’m gaining weight fast. How much is too much? A: Normal BMI (18.5-24.9): 25-35 lbs total. Overweight: 15-25. Underweight: 28-40. Twins: 37-54. Most gain is 2nd/3rd trimester. Discuss with OB [1].

For Dads

• Plan the babymoon together — best window is now through week 28. Pick somewhere accessible, low-Zika, walkable. Balance rest with low-key activities. Document it.
• Reignite date nights — second trimester is energy peak. Plan a dinner out, a hike, a movie. Don’t let baby consume couple identity.
• Research pediatricians — interview 2-3 (Bayside Pediatrics, Washington Township, Palo Alto Medical Foundation). Questions: hours, on-call, hospital affiliation, vaccination policy, after-hours line.
• Read The Expectant Father Ch. 8 — second trimester dad experience, common emotions.
• Pray for continued brain and muscle development — vocal cords active, facial muscles working, intentional prayer for personality emerging.
