Week 11 of pregnancy
Week 11 is early days: much of what happens now is too small to see, and you may be the only one who knows.
About the size of a fig
| Size | About a fig |
|---|---|
| Length | 4.1 cm (1.6 in), measured from the top of the head to the bottom (crown to rump), the way early scans measure |
| Weight | 7 g (0.2 oz) |
| Trimester | First trimester |
| Weeks to go | About 29 to your due date |
These are averages. Every baby grows at their own pace.
What is forming this week
The head is still about half the body's length, and the bones are starting to harden.
How you may feel
For some, nausea eases around now. For others it takes a few more weeks.
Everyone's pregnancy is different. If something worries you, call your midwife or doctor.

Questions
When is the first scan?
In England the NHS offers a dating scan between 10 and 14 weeks. In the US the timing of the first ultrasound depends on your care team, so ask at your first appointment.
Why is pregnancy counted from my last period?
Weeks are counted from the first day of your last period, about two weeks before conception. That is why week 4 is only around two weeks after conception.
Is my baby exactly this size?
No one is. The size, length and weight here are averages from published growth charts. Your scan results are the ones that count, and your midwife or doctor is the person to ask about them.
