Pelvic Floor Health and Pregnancy: A Trimester-by-Trimester Guide

Why Pregnancy Is the Time to Start — Not Wait

Women who proactively support their pelvic floor during pregnancy have significantly better outcomes after delivery. This guide walks you through what's happening to your pelvic floor in each trimester and what you can do to support it.

First Trimester (Weeks 1–12)

What's Happening

Hormonal changes — particularly the rise in relaxin — begin to affect pelvic stability from early in pregnancy. Some women experience increased urinary frequency due to hormonal changes and increased blood volume.

What to Do

  • Learn to identify your pelvic floor muscles with correct technique
  • Begin gentle pelvic floor exercises — 3 sets of 10 slow contractions daily
  • Establish good bladder habits — avoid "just in case" urination
  • Consider seeing a pelvic floor physiotherapist for a prenatal assessment

Second Trimester (Weeks 13–26)

What's Happening

As your uterus grows, downward pressure on your pelvic floor increases significantly. Many women experience their first pregnancy-related bladder leaks during the second trimester.

What to Do

  • Continue pelvic floor exercises — consider increasing to 4–5 sets daily
  • Modify high-impact exercise if you're experiencing leaking
  • Focus on posture and alignment to reduce unnecessary strain
  • Address pelvic girdle pain early if it develops

Third Trimester (Weeks 27–40)

What's Happening

The third trimester brings the greatest physical load on the pelvic floor. Your baby, placenta, and amniotic fluid may add 20–30 pounds of downward pressure.

What to Do

  • Continue pelvic floor exercises, listening to your body
  • Practice perineal massage from around 34 weeks — shown to reduce the risk of severe tearing
  • Discuss breathing and pushing strategies with your midwife or OB
  • Research postpartum pelvic floor rehabilitation so you're ready to start when appropriate

During Labor and Delivery

Worth discussing with your care team: upright positions during pushing, warm compresses on the perineum, and physiological pushing (pushing with your body's urge rather than directed breath-holding) may all reduce pelvic floor trauma.
