Your week-by-week guide to pregnancy: 12 weeks pregnant | MadeForMums

And here's a 3D scan of a 12 week baby...

So what's happening to your body this week?

Let's talk cramps – because they can be scary as hell if you get them (and you haven't the least clue why). At this stage in your pregnancy, it's fairly normal to feel some mild tummy cramps, as your womb shapes up to accommodate your baby's growth.

And it's also normal to feel some sharper pains when you stand up or twist: that's probably just the ligaments that support your womb stretching, as your womb grows.

You can also feel crampy after sex or if you're a bit constipated. Mostly they fade away pretty quickly (if not, or if they come with bleeding, dizziness or intense back pain, do seek medical help). A change of position and a warm shower or bath should ease matters no end.

Is this why you've got a tummy ache?

And is around the weight of... a mushroom

4 things you might need to know this week

MFMer's tip of the week from our forum

“Be warned that dogs know. I went to a meeting last night and one of the girls there just texted me to ask if I'm pregnant as she's 5 weeks and the dog at the meeting was treating us two differently to everyone else in the room. Busted by a super sleuth dog!” - emmarose

Is it normal... to be having weird dreams?

12-weeks-pregnant_week12weird-dreams2new

Boy, is there some weird stuff going on in your head at night. Of course, everyone has strange dreams every now and again, but there's something about being pregnant that takes dreaming to a whole new level of woah. What you're seeing in your sleep is probably way more bizarre and intense than usual – and way easier to recall when you wake up.

Why? No one's really sure. It could be your unconscious trying to process all this pregnancy stuff or it could be that you're simply waking up more in the middle of your dreams (can't get comfortable; need a wee) and that makes them seem more vivid and real.

What does these strange dreams actually mean?

Our preg recipe for week 12 - Quinoa, squash and broccoli salad

12-weeks-pregnant_147545

Why quinoa's great for your growing baby

Yes, it’s a trendy-Wendy ‘super’ grain but, foodie fashion aside, quinoa is actually a properly mega source of protein (beating the socks off any other grain). So, if you’re a veggie (or just not a great meat-eater), cooking with quinoa’s a great way to help you meet your daily pregnant protein needs (about 70g a day). It’s rich in fibre and iron, too.
