Your week-by-week guide to pregnancy: 16 weeks pregnant | MadeForMums

And here's a 3D scan of a 16 week baby...

So what's happening to your body this week?

‘Ooh, me back!’ Yup, you’re suddenly feeling sympathy for those little old ladies who gasp when they stand up and sigh when they sit down. But why? It’s not like you’ve got that much bump to hoick around just yet.

Point the big finger of blame at the (aptly-named) pregnancy hormone relaxin, which is busy loosening your ligaments and joints, making things more prone to twisting and slippage and generally going a bit off-kilter.

Gentle exercise, like swimming, can ease the ache, as can Sensible Susan posture stuff, like not staying in the same position for hours on end, and bending your knees when you’re lifting things up from the floor.

MFMer's tip of the week from our forum

“I'm 16 weeks and still haven't felt anything yet. I did read that it can happen with your 1st baby anytime between 14 weeks and 22 weeks, so that's quite a bit of leeway! I'm hoping to start getting flutters soon” - WOWbabies

Is it normal... to have bleeding gums?

16-weeks-pregnant_week16-brushes-89021267

As you're finding out, bodily fluids love to leak out as your body prepares to have a baby, and bleeding gums are very common during pregnancy.

But don't worry, it's those potent baby-growing hormones AGAIN, this time causing your gums to soften, swell and possibly become inflamed.

So does it mean you give your teeth a brushing break? 'No!', screams every dentist in the country. Perversely you actually need to brush your teeth even more.

Why chocolate is great for your growing baby (yay!)

Ready for the best news ever? Chocolate is good for you – and could work wonders on your baby, too. Oh yes: scientific fact and everything!
