1er mois de grossesse

The test is positive, that's it, you're pregnant! Congratulations! But what does that mean? What's going to happen ? You ask a lot of questions and that is perfectly normal. Motherhood is a new world opening up to you. An infant develops slowly in you and your body changes. While waiting for your happy event, the Madness of the baby accompanies you week after week.

1st month of pregnancy, the madness of the baby accompanies you.

1 st week: (almost) nothing to report

The first few days, nothing indicates that you are pregnant . You probably do not suspect it. No delay of rules (or amenorrhea), no particular pain, your body does nothing to get you the message. Only detail, your breasts may be more swollen or more sensitive than usual, but that's it.

On the other hand, in your womb, the process has already started. The egg has been fertilized, and will divide gradually into two, then into several cells, called blastomeres. This small cluster of blastomeres is the first stage of embryo development . It is called "morula", since it looks like a little blackberry.

The morula will take about 4 days to migrate from the tubes to the uterus. Then, if all goes well, this early embryo attaches to the uterine walls, this is called implantation . At the end of the first week, it measures about 0.1mm.

2 nd week: the time of the test!

It is only after 8 days that you discover that you are pregnant . You wait for your rules and these do not come. This is the moment of the pregnancy test. It will detect, in your body, the presence, or not, of a hormone specific to the pregnant woman, the chorionic gonadotrophic hormone (hCG). It allows the maintenance of the egg and is not secreted until the second week. That's when you learn the good news! Congratulations!

It's time to take good habits . It is advisable to stop drinking alcohol, smoke and be careful what you eat.

Meanwhile in your body, the embryo has doubled in volume up to 0.2m and consists of 150 cells, divided into 3 layers:

  • L’endoderme (couche interne) deviendra le système respiratoire et digestif de l’enfant.
  • Les os, muscles, vaisseaux, reins et organes génitaux seront formés par le mésoderme (couche intermédiaire).
  • L’ectoderme (couche externe) donnera à bébé son cerveau et son système nerveux, mais aussi ses dents et sa peau, poils compris.

3ème semaine : premiers signes

Après une quinzaine de jours, vous êtes véritablement enceinte et vous le sentez. Vous avez des nausées ou des changements d’humeurs fréquents, vos seins sont douloureux, … Pas de panique, ils sont dus à une importante arrivée d’hormones. Votre corps s’adapte aussi progressivement à accueillir son nouvel invité. C’est ce qui explique votre fort appétit ou vos nombreux passages aux toilettes.

Pendant ce temps, l’embryon fait déjà entre 1 et 1.5mm, soit 100 fois sa taille initiale. Il se développe doucement et son cœur commence à se former.

La troisième semaine est aussi le moment de prendre rendez-vous avec un médecin pour une première consultation prénatale.

4ème semaine : un mois de vie intra-utérine

At the 4 th week, your future baby measures 4mm and you begin to communicate with him through the umbilical cord and placenta  ! It's time to watch what you eat if it's not the case yet.

Pregnancy ailments continue and depend on each future mother . Some do not feel anything, others are very tired or have severe nausea. Your hormones can also play tricks and make you cry at the slightest emotion.

The end of the first month is also the time of the first appointment with the gynecologist . He will check with you if this early pregnancy is going well and if your baby is developing properly.
