What is Tiredness in Later Pregnancy?
Tiredness often returns in the third trimester, for different reasons than the hormonal fatigue of early pregnancy. The extra weight you're carrying, disrupted sleep from discomfort or frequent trips to the bathroom, and the physical demands of a growing bump all contribute.
It's a normal part of approaching the end of pregnancy, and many people find that pacing themselves and prioritising rest where possible helps manage it.

Clinical context

Practical steps
Prioritize Rest Where You Can
Later pregnancy tiredness is your body's way of signalling that it needs more support — accepting help and resting when possible is reasonable, not indulgent.
- 1Sleep on your side with support.A pregnancy pillow or regular pillows between the knees and under the bump can improve comfort and sleep quality.
- 2Pace your activities.Spread tasks throughout the day and rest between them rather than pushing through.
- 3Nap when you can.Short daytime naps can help offset disrupted night-time sleep.
- 4Ask for practical support.Delegate household tasks and errands where possible in the final weeks.
- 5Stay gently active.Light activity, like walking, can help energy levels despite the tiredness, as tolerated.
