## How big is the baby at 14 weeks pregnant?

 
At 14 weeks pregnant, your baby is about the size of a peach, roughly 8.7cm and around 43g. The baby can now squint, frown and grimace, and may start sucking their thumb. Fine downy hair called lanugo covers the body to keep warm. These are typical averages — your midwife's measurements are the ones that matter for your pregnancy.

 
## What might you feel at 14 weeks?

 
Most people at 14 weeks notice some mix of the symptoms below — and plenty notice none of them. Your appetite may be noticeably bigger. Round ligament pain — sharp twinges as the uterus stretches — can start. It's normal but mention persistent pain to your midwife. None of this is a diagnosis; contact your midwife if something worries you.

  
### Common symptoms this week

 
 * Bigger appetite
* Round ligament twinges
* Thicker, glossier hair for some
 
 

Symptom lists are typical, never exhaustive — and having none of them is normal too.

  
## What should you do at 14 weeks pregnant?

 
The useful job this week is practical, not medical. Focus on iron-rich foods (lean meat, beans, leafy greens) with vitamin C to help absorption — your blood volume needs it. Pair it with the NHS week-by-week guide if you want a second description of the same stage.

    
### Week 14 checklist
