Your Body at Week 16

For now, it will seem like nothing is happening on the outside — but only for the next couple of weeks. If your timing is right and you've had sex during ovulation, your egg has been fertilized by one lucky sperm and your body is gearing up to host the blastocyst (which will soon become your baby!) that's heading for the uterus, its home for the next nine months.

So what's happening inside this week? Just after the egg is released, the follicle it came from gets a new tenant called the corpus luteum, a yellowish body of cells that occupies the space left by the egg. The corpus luteum starts to produce progesterone and some estrogen, enough of both pregnancy hormones to nourish and support the future baby until the placenta takes over in about 10 weeks

Rapid growth

At 16 weeks pregnant, your uterus is growing at about the same pace as your baby's — aka pretty darn fast! — and it's getting to the point where you may not be able to hide your pregnancy anymore, even if you wanted to.

You're still also likely enjoying the relative bliss of trimester two, especially compared with trimester one, and will soon be able to see more of your baby at your ultrasound in a few weeks.

Week 16 TODO's

  1. Starting consuming foods with high fibre to try and prevent constipation.
  2. Exciting times are ahead, if you need some baby name inspiration be sure to get a book full of baby names and circle any that you and your partner might agree on.
  3. Invest in a carbon monoxide alarm, as this chemical can put not only you but your baby’s development at risk.
