Frequently asked questions from expectant mothers

If you are 10 weeks pregnant with 12 weeks of amenorrhea (absence of menstruation) , congratulations! You are at a key moment in your journey to motherhood, almost at the end of the first trimester . The 10th week of pregnancy is a mix of excitement and questions about your baby's development and your own body.

Baby development at 10 weeks of pregnancy

At 10 weeks pregnant , your baby measures approximately 3 cm and weighs only a few grams, but is changing rapidly each day. Its genitals are beginning to form, although the ultrasound will reveal the sex with certainty, it is not yet possible to determine it. Its main organs continue to develop, and its movements, still invisible to you, are already taking place within the amniotic fluid that protects and nourishes it.

During this period, the mother's blood volume increases to support the baby's growth, which can cause fatigue, dizziness, and nausea in some expectant mothers . These symptoms are indeed normal and reflect your body's adaptation to this wonderful adventure.

Your body at 10 weeks of pregnancy

The 10th week of pregnancy often marks the beginning of small visible transformations: a slightly rounded belly, a changing uterus, more sensitive breasts, and fluctuating energy levels.

This is also the perfect time to take care of your skin and prevent stretch marks with a stretch mark treatment starting in the first trimester . Regularly applying a pregnancy stretch mark oil or cream helps maintain skin elasticity, even as your weight begins to change. For expectant mothers who appreciate practical solutions, a pregnancy kit can contain all the essentials for this stage of the third month of pregnancy, in preparation for the second trimester.

Prenatal checkups at 10 weeks

At 10 weeks of pregnancy , monitoring by a healthcare professional, a midwife or a doctor is strongly recommended, as well as a first examination.

Key exams scheduled for that date include:

Nuchal translucency , measured during ultrasound to assess the risk of Down syndrome and detect possible abnormalities.
Blood tests to monitor your health, to determine your vitamin needs and those of your baby.

These examinations help to reassure and prevent complications, and to better understand any pain related to muscles and changes in the body.

Frequently asked questions from expectant mothers

Can I find out the sex of my baby at 10 weeks?
At this stage, it's not yet possible to say for sure. We'll have to wait until the end of the first trimester or for genetic testing after several more days or weeks for a reliable estimate.

What is happening to my baby at 10 weeks?
At 10 weeks, your baby continues to develop its organs and its features are gradually taking shape. Arms and legs are forming, and it is already moving in the amniotic fluid .

How to reduce the risk of complications?
Follow the advice of your healthcare professional , take your prenatal vitamins, eat a balanced diet and avoid stress, allow yourself moments of reading or rest.

The risk of miscarriage decreases significantly from this period onwards.
