- Your baby
Your baby's now a tiny little blastocyst embedded into the lining of your uterus. The blastocyst is growing and developing thanks to nourishment from your blood system. The inner cell mass is forming the embryo. The ovary which gave up the egg continues to produce progesterone. This ensures the cells on the inside of the uterus support your pregnancy. Each cell builds up and thickens the lining, stimulating the production of hormones.
I'm a little tadpole...
The embryo is about two millimetres long. Tiny, but visible, and shaped something like a tadpole! Your baby's heart begins to beat. And major organs have started to develop. Facial features are starting to form too. Nostrils are becoming distinct and the earliest version of the part of the eyes that is sensitive to light (retinas) is forming. Wow!
See how your baby grows in our week by week image gallery.
Wow. You're pregnant! Congratulations! But are you feeling pregnant? Your breasts may feel tender and your nipples may look a little different. You may also be able to see tiny raised spots (called Montgomery's tubercules) on them. These secrete an oily fluid which prepares your nipple area for feeding. If an earlier pregnancy test was negative - but you still feel you may be pregnant - then take another test, there may be more hormone present now for the test to show a positive result. Yes!
Pregnancy tips: planning on eating for two? Falling pregnant doesn't automatically mean you need to start increasing your food intake. If you start to eat anything and everything you'll most likely gain too much weight. The best advice is to use your common sense. When you need a quick bite, reach for healthy snacks rather than chocolate bars!
