Watch our video to see what your baby looks like this week
The eyes have it this week, as your baby’s eyebrows and eyelashes start to grow, and, beneath those still-fused eyelids, the eyes can now move and detect light. If you could pick your baby up right now, she or he would fit in the palm of your hand.
And here's a 3D scan of a 17 week baby...
So what's happening to your body this week?
Is that a fluttering or the after-effects of a cheeky curry? That first time you feel your baby move in your tummy you're actually likely to miss it. I know, but don't worry – you've got months of this to come.
There's no set time when those first stirrings (or popping as some of our mums describe it) will happen, but for most it's between week 17 and week 22.
Occasionally, the movements are masked by the position of your placenta, but that's unusual. Chances are, the butterflies in your tummy will soon turn into gentle (and then less gentle) kicks.

Is it safe... to fly (and when isn't it)?
Now the barfing has hopefully dried up, do you fancy some warm sun on your face, or a leisurely wander around an exotic city?
If you ignore the UK's fine range of exotic cities, then you're going to need to travel some distance – probably by air.
You can usually fly up as late as 36 weeks (on your way home) – or 32 weeks if you're expecting twins. But do your homework when booking you flights – different airlines have different rules and require different documents.
Our preg recipe for week 17 - Dried fruit energy nuggets
Why apricots are good for your growing baby
Always near the top of any list of pregnancy superfoods, dried apricots punch way above their weight, nutrition-wise. One small handful of these little beauties will, for example, rack up 10% of your daily iron requirement. Dried aprictots also contain folic acid, potassium, calcium, magnesium – and lots of lovely fibre to help ‘unplug’ things that may have got stuck-up.
