Semaine 1 de grossesse

Une traduction française est en préparation. Les informations ci-dessous sont affichées en anglais pour le moment.

Votre bébé cette semaine

Technically, conception has not yet occurred during week 1 — pregnancy is dated from the first day of your last menstrual period (LMP). Your body is already preparing, though: inside the ovaries, several follicles are beginning to mature under the influence of follicle-stimulating hormone (FSH). The uterine lining from the previous cycle is being shed and will soon rebuild into a thick, nutrient-rich endometrium ready to receive a fertilized egg. Think of this week as the quiet starting line of an incredible 40-week journey.

Ce que vous pouvez ressentir

Your period has just started, so you may experience typical menstrual symptoms such as cramping, bloating, and fatigue. Hormone levels of estrogen and progesterone are at their lowest point, which can also affect your mood and energy. Some women notice headaches or lower back pain during this time. Your body is essentially resetting and preparing for a fresh ovulatory cycle. Emotionally, if you are actively trying to conceive, this week can feel both exciting and nerve-wracking.

Symptômes courants

• Menstrual cramps, bloating, and fatigue as your period begins.
• Mood swings due to low estrogen and progesterone levels.
• Lower back pain and headaches may accompany your period.

Conseils de la semaine

Start taking a prenatal vitamin with at least 400-800 mcg of folic acid daily — this is the single most important supplement for preventing neural tube defects like spina bifida, and it is most effective when taken before conception. Cut back on alcohol, tobacco, and excessive caffeine (limit to under 200 mg/day). Eat a balanced diet rich in leafy greens, whole grains, lean protein, and healthy fats to build up your nutritional reserves. Schedule a preconception checkup with your doctor to review medications, vaccinations, and any chronic conditions. Begin tracking your menstrual cycle so you can identify your fertile window in the coming weeks.

Bien manger

• Eat iron-rich foods like spinach, red meat, and lentils to replenish blood loss.
• Include folate-rich foods: dark leafy greens, citrus fruits, and beans.
• Stay hydrated — drink at least 8 glasses of water daily.

Point nutrition

• Start taking 400–800 mcg folic acid daily to prevent neural tube defects.
• Ensure adequate iron intake to compensate for menstrual blood loss.

Bien-être au quotidien

• Light exercise like walking or yoga can help ease menstrual cramps.
• Get 7–9 hours of sleep per night to support hormonal balance.
• Begin tracking your menstrual cycle to identify your fertile window.

Pour votre partenaire

Now is the perfect time to start learning about pregnancy together — pick up a book like "What to Expect When You're Expecting" or browse reputable sites like the Mayo Clinic or ACOG. Offer emotional support, as trying to conceive can be stressful. Consider your own health too: quit smoking, reduce alcohol, and eat well, since paternal health matters for fertility. Help create a calm, positive home environment so you both feel ready for the journey ahead.

Signes à signaler à votre professionnel de santé

• Unusually heavy bleeding soaking through a pad every hour — see a doctor.
• Severe pelvic pain that doesn't improve with rest or pain relief.
