A positive test, a blood test that confirms, and the medical calendar gets underway. Pregnancy spans three trimesters, each with its examinations, ultrasounds, and daily adjustments. However, between official theory and lived reality, some appointments slip under the radar, and recent tests alter the traditional path.
CMV Screening: An Appointment Many Discover Too Late
Among the blood tests in the first trimester, one examination remains poorly known: the CMV serology (cytomegalovirus). This virus, common in adults, can cause neurological damage in the fetus in the case of maternal primary infection.
The HAS has clarified the management protocols: if CMV serology is not performed before 14 weeks of gestation, the screening loses its relevance. In practical terms, this means that this test must be included in the very first blood panel, the one prescribed during the initial consultation.
The result directs two distinct paths. A woman who is already immune (IgG positive, IgM negative) follows standard monitoring. A non-immune woman receives enhanced monitoring with repeated serologies and targeted hygiene measures, such as avoiding contact with the saliva or urine of young children.
This point should be addressed very early with the midwife or doctor. It is possible to access the pregnancy page on Le Portail de la Santé to find the details of the recommended examinations trimester by trimester.
Pregnancy Ultrasounds and Prenatal Tests: What Happens Each Trimester
The three mandatory ultrasounds structure the follow-up, but their role goes beyond just a photo of the baby.
First Trimester: Dating and Screening
The ultrasound between 11 weeks and 13 weeks + 6 days confirms the start date of the pregnancy, detects a possible multiple pregnancy, and measures the nuchal translucency. This measurement, combined with a blood test, feeds into the screening for Down syndrome. The result is expressed as a risk level, not as a diagnosis. A high risk leads to offering a fetal DNA test on maternal blood, or even an amniocentesis.
Second Trimester: Complete Morphology
The morphological ultrasound, around 22 weeks, reviews each organ. The practitioner checks the heart, brain, kidneys, and spine. This is also the time when the location of the placenta is assessed.
Third Trimester: Preparing for Delivery
The last ultrasound evaluates the baby’s position and estimates its weight. A breech baby at 36 weeks may prompt an external version maneuver or a discussion about delivery options. The volume of amniotic fluid is monitored to detect excess or deficiency.
Pregnancy Follow-Up by a Midwife: A Comprehensive and Reimbursed Path
Since 2023, a midwife can provide the entirety of follow-up for a non-pathological pregnancy, from the first consultation to the post-natal visit. This includes prescribing biological tests, ultrasounds, and work stoppages.
The frequency of consultations follows a progressive rhythm:
- One consultation per month until the 30th week of pregnancy.
- One consultation every two to three weeks between 31 and 36 weeks.
- Weekly appointments from 37 weeks until delivery.
Another notable development: teleconsultation. Remote follow-up actions have increased by approximately 21.8% between 2023 and 2024. For an urgent question in the evening or uncertainty about a symptom, a teleconsultation with a midwife is reimbursed just like an in-office consultation.
Early Post-Natal Visit: The Little-Known Package for the First 12 Days
Returning home after childbirth remains a pivotal period. A home follow-up system by a midwife exists, with a package fully covered at 100% by maternity insurance, with no upfront costs.
This visit must be billed within 12 days following childbirth. The midwife checks the healing (cesarean or episiotomy), monitors signs of complications (infection, late hemorrhage), and assesses the mother’s emotional state. The package also covers the follow-up of the newborn: weight, feeding, jaundice screening.
The maternity ward does not systematically offer this appointment at discharge. Requesting the prescription before leaving the maternity ward allows for organizing the visit without delay.
Body and Nutrition During Pregnancy: The Precautions That Really Matter
Dietary recommendations during pregnancy often boil down to a list of prohibitions. A few concrete guidelines help navigate:
- Toxoplasmosis requires avoiding raw meat and washing fruits and vegetables. Non-immune women have monthly serology.
- Listeriosis justifies eliminating raw milk cheeses, smoked salmon, and vacuum-packed deli meats.
- Folic acid (vitamin B9) should ideally be taken from the pregnancy planning stage and during the first trimester to reduce the risk of neural tube defects.
- Iron is monitored through blood tests. Supplementation is only prescribed in cases of proven deficiency, not routinely.
The early prenatal interview remains the best time to ask all these questions. This appointment, distinct from medical consultations, lasts about 45 minutes and covers nutrition, sleep, stress, and working conditions.
Each pregnancy follows a precise medical calendar, but the actual path depends on the chosen professional, serological status, and history. Checking from the first consultation that CMV screening is included in the initial panel, and requesting the post-natal package prescription before leaving the maternity ward, are two simple actions that enhance the quality of follow-up.
