Congratulations, beautiful mama-to-be! Week 4 is a magical milestone — the week many women discover they’re pregnant. Your body has already been quietly nurturing new life, and now, it’s ready to send you those first undeniable signs. Let’s walk through what’s happening inside your body, what you might feel, and how to support your health and emotions during this early, delicate stage.
💫 What’s Happening Inside Your Body
At Week 4, implantation is complete. The fertilized egg (now a blastocyst) has nestled into the uterine lining and is beginning to grow rapidly. This is the week when the placenta starts forming, and hCG (human chorionic gonadotropin) — the hormone pregnancy tests detect — begins to rise.
That’s why, by now, a home pregnancy test might show a positive result!
Your baby at this point is still just a tiny cluster of cells, but oh, what potential it holds! It’s about the size of a poppy seed, and it’s already hard at work forming the amniotic sac, placenta, and soon, major organs.
🌼 Week 4 Pregnancy Symptoms
Every woman’s experience is unique, but here are some common early pregnancy symptoms you might notice:
- Missed period – one of the first clear signs
- Light spotting or implantation bleeding
- Mild cramping or twinges
- Tender or swollen breasts
- Fatigue and sleepiness
- Mood swings or heightened emotions
- Increased urination
- Mild nausea or food aversions
Some women feel absolutely normal at this point, and that’s perfectly okay too.
🤗 Emotional Check-In: It’s Okay to Feel Everything
Week 4 can bring a mix of joy, shock, and even a bit of fear — especially if the pregnancy was a surprise or a long-awaited dream. No matter what you’re feeling right now, know that your emotions are valid.
This is a powerful moment. Be gentle with yourself. 💖
🍽️ What to Do This Week
Here’s how you can support your body and prepare for the weeks ahead:
✅ Take a Home Pregnancy Test
If you haven’t yet, this might be the week to confirm your pregnancy. First-morning urine usually gives the most accurate result.
✅ Start Prenatal Vitamins
Especially folic acid (400–800 mcg/day) to support early neural development.
✅ Eat Well & Stay Hydrated
Now’s the time to start nourishing your body — whole grains, greens, fruits, and proteins will fuel you and your baby.
✅ Avoid Harmful Substances
Say goodbye to alcohol, smoking, and too much caffeine. Also, check with your doctor about any medications you’re taking.
✅ Schedule a Doctor’s Appointment
Once you get a positive test, book your first prenatal visit — usually between weeks 6–8.
💡 Helpful Tips for Week 4
- Start a pregnancy journal to record your thoughts, symptoms, and feelings. These memories will become treasures.
- Get rest — fatigue can hit hard in early pregnancy.
- Create a calm space — maybe a cozy corner to read, reflect, and prepare for this journey.
