Key points to remember from the 4th month of pregnancy
- Renewed energy and blossoming : This beginning of the 2nd trimester often marks the end of nausea and the return of tone, accompanied by a visible "glow" (luminous skin, thick hair).
- Baby development (19 cm / 250 g) : The fetus is growing rapidly, its fingerprints are forming and its senses are awakening; you might feel its first movements as light bubbles.
- Essential skincare routine : To support the rounding of the belly and prevent pregnancy mask, the combination of an anti-stretch mark ritual and SPF 50+ sun protection is crucial.
- Key appointments : This is the time for the 2nd mandatory prenatal consultation, the start of childbirth preparation and, sometimes, the discovery of the baby's sex.
Where are you at 4 months of pregnancy?
Your body finds new energy
The second trimester often brings a sense of relief. The days become lighter, even if your digestion can still be a little temperamental. At this stage, your uterus reaches about 16 cm , which can sometimes slow down digestion and create that feeling of a tight abdomen. To help, regular hydration becomes essential: 1.5 to 2 liters of water per day supports your digestion and reduces discomfort. Some expectant mothers even notice a rapid improvement in their intestinal comfort as soon as they reach this daily amount.
Your skin reacts strongly to the hormones of the fourth month. Sometimes your hormones work wonders. Your hair appears thicker, your nails become stronger, and your skin reflects light better. That famous glow often seen in expectant mothers appears around the fourth month. Let the compliments flow; they feel good, and you deserve them.
Some areas of your skin may darken slightly, and small spots may appear, especially if you are already prone to melasma ( pregnancy mask ). It's known that nearly 70% of pregnant women develop increased sensitivity to UV rays at this stage. Radiant Cream SPF 50+ remains your best bet, even for everyday use! UV rays penetrate clouds and windows. You can discover the face and body care products to adopt during pregnancy to keep your skin comfortable and supple from morning to night.
Your breasts also follow their own rhythm. They increase in size due to the rise in estrogen levels, sometimes up to a cup size . Slight tingling sensations are normal: the milk ducts are gently preparing for breastfeeding.
In terms of how they feel, many expectant mothers experience a real surge of energy during the second trimester , often described as the most comfortable month. Sleep returns, even if some nighttime awakenings persist. Nothing unusual: your baby is growing, and your body is adapting.
Sexual relations remain possible and often enjoyable during this month. Blood flow to the pelvis is better, lubrication is more natural… everything may seem simpler. But there are no rules: some women have a higher sex drive, others less. Listen to your own rhythm without comparing yourself to others.
Your skin needs more comfort
Your belly is changing rapidly: the uterus grows almost 2 cm in height each week. As a result, your skin may feel tight, hot, or itchy, especially in the evening. The Anti-Stretch Mark Ritual , morning and evening, becomes a true haven of comfort.
The Melting Milk , applied in the morning, deeply hydrates while allowing the skin to breathe. It absorbs in less than a minute so you can get dressed immediately.
In the evening, Daylily Sensorial Oil envelops the skin in a protective layer that helps maintain elasticity, an essential point when the belly is growing so quickly. You can further enhance these benefits with the Sublimating Glove : used 1 to 2 times a week , it removes dead skin cells and perfectly prepares the skin for the Anti-Stretch Mark Ritual.
And if you prefer a simple solution, pregnancy kits bring together all these safe care products for pregnancy and breastfeeding, ready to be adopted into your routine.
4 months pregnant: how is your baby developing?
Rapid body growth
At four months pregnant , your baby is settling into a rhythm. Their little body is changing rapidly: they now measure nearly 19 cm and weigh between 200 and 250 g . Their eyelashes, eyebrows, and even fingernails are starting to appear. These are tiny details, but they already offer a glimpse of their future face. Their skin remains very thin and still allows blood vessels to be seen, a sign that everything is falling into place smoothly. Their fingerprints are also forming this month. Tiny ridges, but already a unique identity.
Senses awakened
Your baby is discovering the world in their own way. Taste develops in the amniotic fluid, as does touch : they clench their fist, move their mouth, and explore everything they can. If you feel tiny bubbles or gentle touches, it's often the beginning of the first perceptible movements , especially if this isn't your first pregnancy. Their digestive system is slowly organizing itself: they're even already producing meconium , that first "gift" you'll discover after birth.
Emotional connection
Your baby is beginning to discover your gestures and the sounds around them. They clench their little fist, move their lips, and gradually react to what's happening outside. You can place your hands on your belly when you're relaxed: these simple moments help them feel your presence. If you speak softly or listen to soothing music, they'll already sense this reassuring atmosphere. Nothing technical, nothing "right," just quiet moments where you take the time to breathe .
If you like the idea, you can also wear a pregnancy bola . Its gentle chime will accompany your days, and your baby will eventually recognize it. A small way to create a soft, soothing sound between the two of you.
Your monthly exams: simple, clear, reassuring
Monthly consultation
Your monthly appointment is to check that everything is progressing well. We'll monitor your blood pressure, weight, and fundal height. Some women can already feel Braxton Hicks contractions : they aren't painful and don't dilate the cervix. It's just the uterus gently practicing. Your healthcare provider will also listen to your baby's heartbeat . A few reassuring seconds, with that quick little beat that signals its energy.
4th Month Analysis
A urine test may be recommended to monitor sugar and albumin levels, two useful markers for your health. If you are not immune to toxoplasmosis, the monthly blood tests will continue. Nothing to worry about: simply routine checks to protect you and your baby.
Possible ultrasound of the sex
Sometimes, healthcare professionals offer a sneak peek at the baby's sex around four months . It's never a certainty, as it all depends on the baby's position. You'll get definitive confirmation at your next official ultrasound. In the meantime, just enjoy the anticipation: a little suspense is part of the joys of pregnancy.
Enjoying the 4th month: practical guidelines
Gentle organization of daily life
Your belly is growing, and your nights are changing a little. Sleeping on your side is becoming more comfortable, especially with a nursing pillow placed between your legs or under your belly. Your energy is returning, but you might experience some dizziness or cramps. Your body is working hard. Taking time to rest remains the best way to get through this month with serenity.
Your blood circulation is also changing this month. You might experience some cramps or small varicose veins , especially at the end of the day. Elevating your legs for a few minutes or running cool water over them often helps relieve the sensation. Nothing to worry about, just your body adapting.
Childbirth preparation sessions
The first prenatal classes can begin now. Some women enjoy sophrology, others haptonomy or prenatal singing. These sessions help you better understand your body, your breathing, and your upcoming birth. The goal isn't to anticipate everything, but to feel better supported.
Useful questions to ask your medical team
This month often makes you want to gain a clearer perspective. You can ask:
– how to recognize normal contractions;
– what signs to watch for before the next appointment;
– which lifestyle habits bring you the most comfort.
Your midwife remains your best ally: no question is “stupid”.
