Round ligament pain, possible sciatica, pelvic pain (SPD). Heartburn worse (uterus pushing stomach). Restless legs (urge to move legs at night). Possible hemorrhoids. Carpal tunnel (wrist swelling) [2].

Tips for Week 25

• Heartburn management — small frequent meals, avoid spicy/fatty/acidic, don’t eat 2-3 hrs before bed, elevate head of bed, antacids (Tums, Rolaids) OK with provider. If severe, prescription options.
• Hemorrhoid prevention — fiber (25-30 g/day), water (80-100 oz), no straining, sitz baths, witch hazel pads. Don’t sit for long periods.
• Address sleep — pregnancy pillow, side-sleeping, cool room, limit screens before bed, magnesium glycinate (with provider OK), consistent bedtime.
• Glucose screening — if not done at 24 weeks, do this week. 50g Glucola, 1-hour test.

Things To Do (Checklist)

• Get glucose screening if not yet done
• Address heartburn: small meals, antacids, head elevation
• Treat hemorrhoids if present
• Optimize sleep: pregnancy pillow, side-sleeping, routine
• Continue daily kick counting (10 in 2 hrs)
• Cyst: continue to monitor; note any size changes at next scan

Frequently Asked Questions

Q: I’m getting carpal tunnel. Is that permanent? A: No. Pregnancy-induced carpal tunnel usually resolves post-birth. Wrist splints (neutral position), elevation, avoid repetitive motion, acupuncture. If severe, OB can refer to hand surgeon [1].

Q: I have insomnia. Help? A: Common in third trimester. Sleep hygiene: consistent bedtime, cool room, no screens 1 hr before, magnesium glycinate (200-400 mg), Unisom (with provider OK). If anxiety-driven, talk to OB [2].

Q: Why am I short of breath? A: Uterus pushing diaphragm up, lung capacity reduced. Slow down, rest more, sit up straight, sleep propped up. If severe, sudden, or with chest pain, call OB [1].

For Dads

• Cook anti-heartburn meals — bland, low-fat, low-acid. Avoid trigger foods your partner identifies. Smaller portions, more frequent.
• Manage “reflux-friendly” dinner timing — last meal 2-3 hours before bed. Help with prep/cleanup so she can rest upright.
• Research infant CPR — class at your area Red Cross, Valley Medical, or private. Many options; book for 30-32 weeks.
• Read The Expectant Father Ch. 22-23 — third trimester transition, your role with newborn, sleep deprivation preview.
• Pray for continued brain and spine development — the spine and nervous system are intricate, intentional, beautiful.
