What does my baby look like?
Your tiny person is 9mm, about the size of a little fingernail now.
The outer layer of the cushiony amniotic sac develops into the placenta. Its cells grow deep into the wall of your womb, creating a rich blood supply.
Your placenta will give your baby nutrients and oxygen through their umbilical cord. It has three vessels: One thick vessel carrying oxygenated blood and nutrients to the baby (they won’t breathe through their lungs until they're born), and two thinner vessels that carry blood containing waste-products back into your circulatory system.

Been craving any crazy concoctions? Or maybe you’ve taken a sudden dislike to one of your favourite foods? Cravings aren’t uncommon in pregnancy but don’t be alarmed if you don’t get any, that’s totally normal too. Read about the 10 most-common pregnancy myths.
Actions to take
Choosing the best nutrition for you and your baby
You might not feel pregnant yet, but it’s time to start looking after yourself and your precious cargo. This week we're looking at food and nutrition in pregnancy.
Your body is working hard to grow a baby but it’s super-efficient, which means there’s no need to ‘eat for two’. You won’t need to up the calories until your final trimester (and that’s just by 200 calories a day). Tackle pregnancy munchies by eating small meals often to keep your blood sugar levels steady.
Find out what 200 calories looks like.
Eating a healthy, balanced diet in pregnancy will give you more energy and ensure your baby gets all the nutrients it needs.
“I used to eat a lot of junk food, but when I was pregnant I took healthy snacks to work instead - fruit, yoghurts and almonds - and I drank a lot of water.”

What foods are off limits?
At first trying to remember all the dos and don’ts in pregnancy – like which foods to avoid - feels like navigating a minefield. But don’t, you’ll soon get to grips with it. We’ve got lots of info to make it as straightforward as possible.
Read our tips to avoid food poisoning.
Vegetarian or vegan?
It’s perfectly possible to follow a vegetarian or vegan diet in pregnancy but it’s important to ensure it is varied and includes all the food groups. Learn more about planning your vegetarian or vegan diet to ensure your baby gets enough vitamin B12, riboflavin, iron, zinc, calcium and iodine.
Cutting down on caffeine
It’s important to limit your caffeine intake now that you’re pregnant. You might be surprised to learn that caffeine is not just found in coffee, but also in tea, chocolate and energy drinks! Decaffeinated tea and coffee, fruit juice or water are all good choices if you are used to drinking a lot of caffeinated drinks. Find out how much caffeine is in your daily diet.

Hi. I'm 5 weeks pregnant and blood group o negative. I have had an ectopic pregnancy and a missed miscarriage (10 weeks) in the past. Following both of my losses I was never given anti d injections. I'm now worried that this might impact on this pregnancy. Is my baby at risk due to my blood rh negative status?

Hi Lesley, The guidelines state that anti D does not need to be given after a miscarriage before 12 weeks. https://www.rcog.org.uk/en/guidelines-research-services/guidelines/anti-d-after-miscarriage---query-bank/
When you go for your first set of routine blood tests usually before your 12 week scan, they will test to check that you don't have any abnormal antibodies in your blood. You will then be advised to have a routine injection of anti D at 28 weeks.
