1st month of pregnancy: Tips for starting your new life

May 03, 2025 Cédric Freppel

You had some suspicions, and a pregnancy test has just confirmed them by revealing a pretty cross: you are pregnant! Congratulations, a great adventure begins ! 

Between intense joy and uncertainties, you don't always know what awaits you during this first month of pregnancy and beyond - especially if it's your first child! Even if you don't necessarily feel it, your body is experiencing major upheavals during this first month, the first signs of the big changes that await you! Follow the guide, we'll explain what's happening to you and this little fetus during the first weeks of gestation.

  1. 1st month of pregnancy: a month that goes by very quickly!
  2. 1st month of pregnancy: the changes that await you
  3. 1st month of pregnancy: changes in your future baby
  4. 1st month of pregnancy: forward to a new life!

1st month of pregnancy: a month that goes by very quickly!

The first month of pregnancy passes very quickly for many pregnant women, and for good reason: it takes around two weeks for the body to begin to secrete the hCG hormone – the famous pregnancy hormone – in quantities large enough for it is detectable by a pregnancy test.

Those who monitor their cycles closely will therefore learn the good news after fifteen days of gestation, but for others, who have irregular cycles or who are not particularly trying to baby, this first month of pregnancy can easily pass. unnoticed for some time yet! 

It is customary to designate the progress of pregnancy in SA – weeks of amenorrhea , that is to say the number of weeks elapsed since the first day of the last period. We know, this calculation is not easy at first, but you will quickly get used to it!

So, at 15 days pregnant, you are two weeks pregnant (2SG) but already 4 weeks amenorrhea (4WS). The first month of pregnancy therefore goes from 2 weeks to 6 weeks, and a full-term pregnancy lasts 41 weeks. I promise, you will quickly know how to count in SA

1st month of pregnancy: the changes that await you

During this first month of pregnancy, you may notice greater fatigue than usual, you may have cravings or mood swings ... Which is hardly surprising because the hormones are racing. , And that's just the beginning ! 

You may feel some tightness in the lower abdomen, especially if it is a first baby: the uterus stretches, reaching the size of a clementine at the end of the first month of pregnancy. …You will notice that your breasts are tighter , more sensitive, and even that they are starting to gain volume. Stay tuned to your body and these first changes, and take the opportunity to rest as much as possible ! 

Daylily Paris is a brand of clean, sensorial and effective skincare products, made in France and 100% compatible with pregnancy and breastfeeding. We're also committed to sharing quality information for an enlightened and relaxed maternity. 🧡

In addition to the absence of periods, you may notice increased vaginal secretions (their role is to protect the vagina against infections), and sometimes very light bleeding (which can accompany the implantation of the embryo into the mucosa) : they are not worrying if they remain minimal and if they are not accompanied by pain or other symptoms. 

This early pregnancy can be a little confusing because many women have no pregnancy symptoms and don't feel "pregnant." For some, this first month as a future mother even goes completely unnoticed! Don't worry if you don't feel nauseous (it's still too early and that's an excellent reason to rejoice!), if you feel exactly as usual: this is completely normal, and nothing to worry about. 

Be sure, however, whether symptoms or not, your body is experiencing major internal changes to welcome this little embryo as it should!

1st month of pregnancy: changes in your future baby

Being pregnant means living as a couple in the same body, at the same rhythm.

After implantation (that is to say the implantation of the embryo in the uterine lining), the egg divides into several parts which will form the placenta and the fetus. 

From the third week of pregnancy, the embryo doubles in size every day ! Realize: at 3 weeks pregnant,  it is as big as a sesame seed, at the end of the first month a week later, it will reach 4 to 5mm long, that is to say the size of a lentil! 

It is during the first month that a fundamental change takes place for baby: his little heart begins to beat during the third week of pregnancy. Be patient, you will soon be able to hear it! 

At 6SA, its different organs are put into place : the spine, the lungs, the digestive tracts begin to take shape. The embryo gradually takes on a curved shape like a small bean, and continues to grow at great speed: it thus becomes visible on the ultrasound !

1st month of pregnancy: forward to a new life!

The announcement of your pregnancy turns your life and your daily life upside down and brings its share of changes.

Let's start with the small restrictions that await future mothers, for a good cause of course! 

From now on, there is no question of consuming a drop of alcohol ! Water is your best ally, sufficient consumption is absolutely necessary for the proper development of the fetus. Tobacco consumption is also not recommended , do not hesitate to consult a specialist who can help you reduce or stop smoking. 

There is also no question of taking medications without consulting your doctor: many of them are prohibited for pregnant women, or should only be ingested on medical advice. 

You will also need to pay attention to the products you use on a daily basis : in particular essential oils, which can have a deleterious effect on this little fetus, but also endocrine disruptors, solvents, pesticides, etc. which should be avoided as much as possible. 

In the bathroom, to continue pampering yourself, consider Daylily care products which are designed especially for pregnant women, without harmful ingredients, neither for you nor for your little tenant. 

And of course you can now adopt a particularly careful diet , limiting fat and sugar. As the saying goes, “When you're pregnant, you shouldn't eat twice as much, you should eat twice as much!” " We count on you ;-) 

As soon as you announce your pregnancy, make an appointment with your gynecologist or the doctor who will monitor your pregnancy. He or she will schedule a long-awaited appointment for you, that of the first ultrasound, around the six weeks of pregnancy. It's frustrating, but we'll have to wait a little longer to check that everything is in order and hear that little heart beat for the first time 

No paperwork this month : it is also on the occasion of this visit that we  will give you the pregnancy declaration documents. 

In the meantime, take full advantage of this tender news, and no one will blame you if you don't plan to come down from your little cloud yet!
