What are the body changes for the mother-to-be at 4 months of pregnancy?

The months go by and they don't look the same, to say the least. At 4 months of pregnancy , your belly begins to round out and your skin becomes tighter and tighter . We tell you more about the anti-stretch mark routine at the bottom of this article.

Your nausea and fatigue disappear little by little, you can finally breathe! The heartburn and bloating still linger for a while.

You will also experience the famous pregnancy mask ! Remember to protect your skin as soon as you expose yourself to the sun (summer and winter) to get through it. It is hyperpigmentation of the skin which can give rise to brown spots around the mouth, above the eyebrows and on the side of the breasts. In fact, nothing serious for the mother. The problem is that if these spots appear, they can reappear with the slightest ray of sunlight throughout your life...

Apart from this pregnancy mask, you will experience what is commonly called “ the pregnant woman’s glow ”. Your skin and its complexion will brighten and your hair will be supple, hydrated and more beautiful than ever! Enjoy!

You will also experience rather heavy white discharge . Monitor them and at the slightest tingling when you urinate, consult a health specialist. An infection could be very serious at this stage of pregnancy.

Diet during the 4th month of pregnancy

To ease heartburn or bloating, try eating light meals in small portions . To do this, eat several small meals with nutritious foods (proteins, vegetables, starchy foods). Remember to drink plenty of water to aid digestion and limit constipation.

Continue to eat a balanced diet while treating yourself to small pleasures from time to time. It's not a question of getting frustrated but rather of finding a balance that provides you with all the nutrients your baby needs to continue growing properly.

Feeling baby for the first time… around 4 months of pregnancy

Around 16-18 weeks, the mother-to-be begins to feel her baby move for the first time , what emotions... The baby's first “movements” will feel like little bubbles in the belly. At the end of the 4th month of pregnancy, you may be able to feel the first kicks. Share it with the person supporting you during your pregnancy, it's a moment of pure magic!

And the rest …

The second trimester of pregnancy (between the 4th month of pregnancy and the 6th month) is the best time to prepare for the arrival of your baby . Whether it's shopping, preparing the house or your room, do as much as possible during the 2nd trimester.

It's also a good time to take full advantage of your relationship through dates for two, weekend getaways and even trips if you can. Your life will soon change and at first you will surely have fewer calm moments together. If you already have one or more children, start introducing them to the news if you haven't already. Indeed, it’s a big change for them too! If you can't find the words, several books will do it very well for you.

After three months where you were a little tired and nauseous with a libido at half mast, it comes back! Now is the time to take the opportunity to tell your other half what you want.
