You are now
You are now
Your baby is starting to look more human-like. It's about the size of a large grape. Sweet! The limb buds are growing quickly and look more like arms and legs, with little separations for your baby's tiny toes and fingers. Your baby's face is also beginning to form. The nostrils, lips and mouth are appearing and your baby's eyes are developing underneath the skin.
Your baby's nervous system develops rapidly at this time too, especially the spinal cord and brain. Brain waves can be measured now, and the head is getting bigger as the brain develops - much larger in proportion to the rest of the body. All organs have started to form and are in the right position. Your baby's heart is beating fast - it'll show up on a scan if you have one. The embryo is now officially a foetus.

If you're not already feeling tired, now is the time that fatigue will probably start - so make sure you get up close and personal with your sofa more often! Even though you don't look pregnant yet (all in good time), there's lots going on behind the scenes. Your body is working extremely hard. Your breasts will start to swell to get ready for breastfeeding - they could grow up to four times their size in the next nine months - yay! You may have a scan around this time to check you're pregnant (if there's any doubt). The scan will also check that the pregnancy is not ectopic. You'll have your dates confirmed too.
Pregnancy tips: as soon as you find out you're pregnant it's hard to keep it to yourself. Most parents-to-be wait until after week 12 as this is when the risk of miscarriage falls. But it's totally up to you. You may just want to tell close family and friends - as they're probably the people you'd tell if the pregnancy were to miscarry.
