1. Pregnancy Week 4: What’s Happening in Your Body?
Around this time, a fertilized egg has implanted in your uterus, and the placenta is starting to form. Your body is producing hCG (the pregnancy hormone), which is what pregnancy tests detect. Even though it’s early, this hormone surge may already cause subtle changes.
2. Symptoms to Expect at Week 4 of Pregnancy
Some women feel completely normal, while others notice early signs such as:
- Light spotting (implantation bleeding)
- Breast tenderness or fullness
- Mild cramping or bloating
- Fatigue
- Increased sense of smell
Every woman’s body is different. Not having symptoms yet is totally normal too.
3. Week 4 Pregnancy Tips: Confirm & Prepare
If you’ve missed your period and tested positive, now’s a great time to:
- Schedule your first prenatal appointment
- Start taking prenatal vitamins with folic acid
- Avoid alcohol, smoking, and harmful substances
- Adopt a balanced, nutrient-rich diet
4. Emotional Changes During Week 4 of Pregnancy
It’s okay to feel excited, nervous, or overwhelmed—all at once. Mood swings may begin due to hormones, but journaling, resting, or talking to someone you trust can help you stay grounded.
5. Pregnancy Week 4: What to Avoid
Now’s the time to be cautious with:
- Medications not approved by your doctor
- Raw or undercooked meats and fish
- Unpasteurized dairy products
- Excess caffeine (limit to 200 mg/day)
6. What Happens Next in Pregnancy Week 5?
Your baby’s development accelerates next week with the early formation of major organs. Hormones rise, and symptoms may intensify. Each week brings new changes and milestones.
Pregnancy Week 4 is all about confirmation, caution, and care. It may feel uneventful on the outside, but inside, life is taking root. Be gentle with yourself, stay hydrated, and begin creating healthy routines for the weeks ahead.
