Your Pregnancy at Week 4

by Your Baby Club

Have you peed on a stick yet? Do you even know you are pregnant? Probably not! You’ll likely soon be entering your next cycle and won't yet know if you've missed a period.

Bizarrely, in weeks 1-3 of pregnancy you are still in the process actually getting pregnant as those first weeks take into account your monthly cycle and start with preparing your womb for a possible tenant! It's not until week 3 when you likely ovulate that you can actually get pregnant. Obviously, if you do not fall pregnant all those preparations are discarded with your next period and replenished the next month.

However, if sperm met egg and fertilised and that once single-cell began multiplying as it made its way down your tubes, at week four, your body will be getting busy with implantation. This happens around 6-12 days after conception and may be indicated by a little spotting as the blastocyst buries itself and attaches to your uterine wall and gets acclimatised to its new surroundings.

Depending on the number of days in your monthly cycle, you likely conceived around 1-2 weeks ago and your tiny human is currently no bigger than a pinhead! Yet, in eight months time, your gorgeous baby will fill a baby grow! How cool is that!

This little pinhead is growing at an unbelievable rate and the fertilised egg is dividing over and over to form all the different parts of his or her body, as it gets itself comfy in the womb.

As the baby’s blood vessels start to form, so too does their blood begin to circulate and help with the development of their tiny heart. For the next few weeks, your baby is an embryo and takes all the nourishment it needs from the yolk sac (and you!). Once you are around 12-14 weeks pregnant the placenta will be fully formed and ready to take over all the hard work, this is when you'll start getting your energy back.


In terms of how you are feeling? The likelihood is you will feel pretty normal as pregnancy symptoms don’t tend to rear their heads for a few weeks yet. Here's a list of what to expect in early pregnancy. So, sit back, take a big breath and relax as your body does all the hard work!
