Pregnancy: medical monitoring trimester by trimester

IRIS Prévention
7 October 2026
Pregnancy is punctuated by appointments which monitor, month after month, the health of the mother and child. A reassuring thread to follow.

Expecting a child is accompanied by well-organized medical monitoring, spread throughout the three trimesters. Monthly consultations, ultrasounds, exams: this course aims to support the pregnancy, prevent complications and prepare for childbirth. Knowing the main stages helps you live this period more peacefully.

1. The first trimester: confirm and secure

The start of the pregnancy includes a first consultation, blood tests and a first ultrasound (called dating) which specifies the term. It is also the time for lifestyle advice and prevention (stopping alcohol and tobacco, recommended supplementation).

2. The second trimester: monitor development

3ePreparation for birth, monitoring

The second trimester is marked by morphological ultrasound, which examines the baby's development. Monthly consultations continue, with blood pressure monitoring and screenings offered.

3. The third trimester: preparing for childbirth

The last trimester intensifies surveillance as the term approaches. An ultrasound assesses the baby's growth and position. Preparation for birth and consultations with the maternity ward complete this follow-up.

4. Shared and personalized monitoring

Monitoring can be provided by different professionals (midwife, doctor, gynecologist) depending on the level of risk. Some pregnancies require close monitoring. The main thing is not to miss any appointments and to report any unusual symptoms.

    • Respect the consultation and ultrasound schedule
    • Report any unusual symptoms without delay
    • Rely on the professionals who support the pregnancy

This course, medically supervised, aims for the well-being of the mother and child at each stage.

    • The 2nd trimester includes morphological ultrasound which examines the baby's development.
    • The 3rd trimester intensifies monitoring and prepares for childbirth.
    • I respect the appointment schedule and I report any unusual symptoms: follow-up can be ensured by a midwife, doctor or gynecologist.
