Your body is producing bucket loads of pregnancy hormones, and your baby is growing faster than it will at any other time of your pregnancy. -
4 weeks pregnant
Your growing baby is not even 3mm long yet and still not much bigger than a poppy seed. Despite the tiny size there’s plenty going on as the embryo splits into three different sections.
In one section the brain and central nervous system are already beginning to take shape as their neural tubes develop. In the other two sections, the heart and circulatory system are already beginning to form and the lungs and intestines are in the very early stages of development. -
6 weeks pregnant
If you can imagine a tiny poppy seed, that’s the size of your growing baby's heart now. Around week six their heart is changing from being a simple, single tube to a complex four chamber organ which will pump blood around their body. How amazing! At six weeks the heartbeat of your baby might be detectable by an ultrasound – it’s currently beating at around 160 beats per minute – almost twice as fast as your heart. Your baby will now be covered by a thin layer of see-through skin. -

Your baby’s tiny little fingers and toes will have formed, right now they are webbed and will continue to be so for several weeks, baby’s lungs are developing this week, with the breathing tube -

Your baby's little heart is now fully formed. round the 10 week stage your baby is also beginning to swallow fluid, produce digestive juices and kick their limbs - if you see your baby on an ultrasound scan at 10 weeks, they will be making jerky movements and bobbing about! -
12 weeks pregnant
Last week of The first trimester.
She may weigh as much as half an ounce. This begins the age when the fetus starts to look really cut in those womb pictures. If you had a womb camera, you'd be able to see your baby's proportions changing, with the growth of the head slowing down to let the rest of the body catch up. Arms, legs, and fingers are also growing out and tapering to look more like a newborn's, and your baby's posture becomes less curled and more upright. -
