4 weeks pregnant (6 weeks gestation): a tiny being already well settled in
Welcome to your first month of pregnancy ! At 4 weeks pregnant (6 weeks gestation) , it's often the magical moment when the expectant mother discovers she's having a baby 💕. Did your test just turn positive? Congratulations! It's often an emotional announcement to share with your partner . Even if your body isn't showing any visible signs yet, like weight gain, everything is already happening inside: your future baby is growing at an incredible rate, and your body is transforming to welcome them properly.
What happens in your body at 4 weeks of pregnancy
At this stage, the hCG hormone , produced by the developing placenta , becomes easily detectable from the fourth week of pregnancy. This is what pregnancy tests detect, and it is responsible for most of the pregnancy symptoms you may begin to experience.
-
More pronounced fatigue
-
Morning sickness (often upon waking),
-
Tender or more sensitive breasts ,
-
Slight twinges in the lower abdomen,
-
Hypersensitivity to smells , sometimes accompanied by a sensation of a sensitive or lumpy throat
-
And of course, no rules .
These signs simply show that your body is adapting to its new mission: nourishing and protecting your future baby, which can also lead to mood changes and normal emotional swings in early pregnancy.
But don't worry if you don't feel anything right now; every woman is different, and reading articles can also help you better understand these early stages of pregnancy. For some pregnant women , symptoms appear later, and that's perfectly normal 🌿.
Your uterus is slowly beginning to change: its lining is thickening to accommodate the embryo, blood circulation is increasing, and the cervix is closing tightly. Meanwhile, the placenta is starting to form from the trophoblast (the outer layer of the embryo). It will produce the hCG hormone and, in the coming weeks, ensure the vital exchanges between you and your baby.
Your baby's development
At 4 weeks pregnant , your embryo measures barely 1.5 to 2 mm , about the size of a poppy seed ! It has grown a few millimeters since the 3rd week of pregnancy . And yet, it's already a veritable little factory for life 💕.
After traveling from the fallopian tube , the embryo has successfully implanted in the wall of your uterus. It is now surrounded by two important structures:
-
the yolk sac , which nourishes it before the placenta is fully functional,
-
and the amniotic cavity , where it already floats in a light protective fluid.
Inside, everything is being organized at high speed:
-
The neural tube begins to form. It will give rise to the nervous system : the brain, the spinal cord and the vertebral column .
-
The umbilical cord begins to form, connecting the unborn baby to the placenta.
-
The heart is already forming and will start beating very soon ❤️, a moment often confirmed during the first ultrasound , where we still talk about a fetus in the very early stages of development.
-
The three layers of cells in the embryo (ectoderm, mesoderm, endoderm) differentiate: each will give rise to different organs (skin, muscles, digestive system, etc.).
It's a tiny but crucial period: in just a few days, the entire "blueprint" of the human body is put in place. Incredible, isn't it?
How can we best support these first few weeks?
During these first weeks of amenorrhea , your role is to take care of yourself , gently but surely. Here are some simple and effective tips to help you through these early stages of pregnancy:
🍊 Adopt a diet rich in fruits and vegetables to stock up on vitamins and minerals. Foods containing vitamin B9 (folic acid) are particularly important: they contribute to the proper formation of the neural tube .
🧘♀️ Rest as soon as possible. Fatigue is normal: your body is expending a lot of energy to support the development of the embryo .
👩⚕️ Consult a healthcare professional (doctor, gynecologist or midwife ) now to schedule your first pregnancy follow-up, set a consultation date and ensure that everything is going well.
💧 And also remember to take care of your skin by using products to prevent stretch marks : it's the perfect time to adopt a gentle and natural routine.
For example, you can use a nourishing pregnancy stretch mark oil , or alternate with a pregnancy stretch mark cream.

Stay attuned to your body
Most pregnancies go perfectly well. But certain signs should encourage you to consult a healthcare professional without delay:
-
Severe abdominal pain ,
-
Significant bleeding ,
-
Or any unusual symptom .
These signs can, in rare cases, indicate an ectopic pregnancy (when the embryo implants in the fallopian tube instead of the uterus). In this case, prompt medical attention is necessary for your safety.
In summary
At 4 weeks pregnant (6 weeks gestation) , your body and your future baby are already working hand in hand.
The hCG hormone continues to increase, the placenta is forming, and the development of the embryo continues: neural tube , umbilical cord , nervous system , spinal column … everything is starting to take shape.
Even if nothing is visible yet, everything is already happening inside.
So listen to your body, rest, eat healthily, and above all: enjoy this unique moment 🌸.
