Fundal Height at 25 Weeks: What Your Provider Is Measuring

From approximately 20 weeks, your provider measures fundal height at each appointment — the distance in centimeters from the pubic bone to the top of the uterus. This simple measurement tracks fetal growth between ultrasounds.

What's normal: Fundal height in centimeters roughly equals gestational age in weeks (±2 cm). At 25 weeks, a measurement of 23–27 cm is within the normal range. Measurements consistently above or below this range prompt an ultrasound growth scan rather than immediate concern.

Late second trimester priorities at 25 weeks:

Glucose test deadline approaching: If not yet done, the gestational diabetes screen must be completed by week 28. Schedule it now if you haven't.
Kick counting begins soon: Formal kick counting (10 movements in 2 hours) is typically recommended from week 26–28. At 25 weeks, begin familiarizing yourself with your baby's normal movement pattern.
Iron levels: Many providers do a blood count at the 25–28 week appointment. Low ferritin at this stage causes fatigue that compounds third-trimester exhaustion.
Pelvic girdle pain: Increasing pelvic pain at 25 weeks is common. Early physiotherapy referral is more effective than managing it alone — ask at your next appointment.

See week 26 for the viability milestone and what it means.

🥗 Nutrition focus

Fiber 25–30g/day is essential now — prevents hemorrhoids, which affect 85% of pregnant women
Stay well hydrated — constipation worsens hemorrhoids significantly
Vitamin E-rich foods (sunflower seeds, almonds, spinach) support skin elasticity

What trimester is 25 weeks pregnant?+

25 weeks is in the second trimester (weeks 14–27). The third trimester begins at week 28. You have approximately 15 weeks until your due date.

What is fundal height and what should it be at 25 weeks?+

Fundal height is the measurement from your pubic bone to the top of the uterus in centimeters. At 25 weeks, a measurement of 23–27 cm is within normal range (roughly equal to gestational age in weeks ±2 cm). Consistently small or large measurements trigger an ultrasound growth scan.

When should I start the glucose tolerance test?+

The glucose tolerance test (GTT) for gestational diabetes is scheduled between weeks 24–28. At 25 weeks, if you haven't scheduled it, do so immediately — it must be completed before week 28. The 1-hour glucose challenge test doesn't require fasting and takes about 1 hour total.
