13 Weeks Pregnant – What You Need to Know

13 Weeks Pregnant

At a glance:

  • Your baby's reproductive organs are fully developed
  • Hormones are still raging
  • Your placenta is fully developed

What’s happening to your baby

She’ll start looking more and more like a normal baby, although her head will still appear proportionally pretty big compared to the rest of her body, and at about 7cm long, will still only weigh 23g.

Your baby’s reproductive organs will be fully developed inside her body – she’ll already have – gasp - two million eggs in her ovaries.

If you’re having a boy, his testes will be developed and his penis will be forming outside his body. However, even on an ultrasound scan, you probably won’t be able to tell the sex yet. However, you can have fun reading through the old ways people tried to predict the gender of coming babies

What’s happening to you

Symptoms such as morning sickness and exhaustion should begin to abate now you’ve reached your second trimester, leaving you beoyed up on hormones and feeling fantastic (well that’s the theory, anyway!)

Hormones can affect the condition of your hair, and whether you end up with a greasy do and spots or shiny hair and a glowing complexion is, unfortunately, very much down to the luck of the draw. But whatever the state of your hair or complexion, there’s loads of lovely products to give you a pick-me-up if you need it.

By now, your placenta will be fully developed, but will continue to grow in size throughout your pregnancy. Your baby is connected to it via the umbilical cord, through which your baby gets enough oxygen and nutrients.

It also gets rid of waste products such as carbon dioxide and is responsible for producing many of the important hormones needed for your baby’s development. It might not be very pretty to look at (don’t Google image it if you’re feeling delicate!) but it does a truly amazing job for your baby.

The Signs That The Pregnancy Hormones Have Definitely Hit

What to prepare for

Starting to see your bump! It shows up between weeks 12 and 16, so chances are you will soon have another striking realisation that this actually is happening. A showing bump can be one of the biggest pregnancy excitements. By next week you will probably have all that queasiness fully abated so you can focus on enjoying your pregnancy and, if you still haven't, announce to everyone that you are expecting.
