Week 1 – 4 of your pregnancy: What to expect?

Apps by Annie

The beginning of something new is always a unique life experience. This absolutely strikes home when it comes to pregnancy. Every new mother is curious to know about the process. That’s why we prepared a series about the weeks of pregnancy. Let’s start right now!  

Week 1


The last day of your menstruation officially marks the start of your pregnancy, although you won’t be able to tell for another couple of weeks. If you were trying to conceive, the best thing you can do is stop smoking and drinking alcohol and start eating a lot of fruit, vegetables and other healthy food. Think like a future mother, don’t stress over the small stuff and you’ll be absolutely fine. Just keep calm and look forward to your baby!

Week 2


Some women may feel a slight pain in their underbellies during the second week of pregnancy and you might too. But don’t worry, it’s not a bad sign. Your uterus is adjusting to the fertilized egg growing new blood perfusion mucus membranes that will take care of the fertilized egg and feed it for the next few months.

If you know that you are pregnant (but most women know from week 3 or 4), you might start wondering about the baby’s gender straight away. There are no ways to know if you’re having a girl or a boy so soon, all advice that is ‘guaranteed’ is just superstitions at this point.

Week 3


The sperm has definitely merged with the egg at this point and has been adopted by your womb which will carry it for the next nine months. No-one can tell that you’re pregnant yet but your body is undergoing major changes to accommodate the life growing inside of you.

You can start to notice some small weight gain, around 1 to 2 pounds by now. As the baby develops over time, the changes will get bigger.

Week 4


Your baby measures about 1 mm by now and gets all the nutrients it needs form your uterus. Make sure you eat a lot of healthy foods and enough nutrients to sustain its growth.

The fertilized egg stays in a space called the blastocyst attached to the uterus. The blastocyst produces the hormone called HCG (the human chorionic gonadotropin). So this is the week you can take a home pregnancy test to find out if you’re pregnant, because your HCG levels will be high enough for the test to detect.

You may experience weak bleeding during the 4th week because of the embryo implanting itself into the lining of your uterus.
