👶 Fetal Development at 7 Weeks Pregnant
At 7 weeks, your embryo is about the size of a blueberry—around 10 mm long. Despite its tiny size, massive developmental changes are underway.
What’s Happening This Week?
According to ACOG:
- Brain Development: The brain is growing at a fast pace, with the formation of the cerebral hemispheres.
- Limb Growth: Arms and legs are forming, and tiny paddles at the ends will soon become fingers and toes.
- Facial Features: Nostrils, mouth, and eye lenses are beginning to form.
- Heartbeat: Your baby’s heart is beating around 120–160 beats per minute, which may be detected via ultrasound.
This stage is critical, and proper prenatal care is essential to support the development of your baby’s organs and systems.
🤰 7 Weeks Pregnant Symptoms
Pregnancy symptoms often intensify at this point due to rising levels of hCG (human chorionic gonadotropin) and progesterone. Each pregnancy is unique, but here are the most common symptoms at 7 weeks:
🌿 Common 7 Weeks Pregnant Symptoms:
- Nausea and Vomiting (Morning Sickness)
A hallmark of early pregnancy, nausea can be triggered by smells, foods, or even hunger. Ginger tea and vitamin B6 supplements may help. - Fatigue
You may feel exhausted due to hormonal shifts and the body’s effort to support the embryo. - Breast Tenderness and Growth
Your breasts may feel heavier and sore as the body prepares for breastfeeding. - Frequent Urination
Hormones increase blood flow to the kidneys, and your uterus begins to press against the bladder. - Mild Cramping or Spotting
Some women experience light cramps or spotting. According to NHS, mild spotting is common, but always report heavy bleeding or severe pain. - Bloating and Gas
Progesterone relaxes muscles, including the digestive tract, leading to bloating. - Food Cravings or Aversions
You might start disliking foods you once loved or craving unusual combinations.

🤰 7 Weeks Pregnant Belly: What to Expect
At 7 weeks, your belly likely hasn’t “popped” yet, especially if it’s your first pregnancy. However, bloating and uterine growth might make your pants feel tighter.
Belly Changes:
- Uterus Expansion: Your uterus has doubled in size since conception and is about the size of a lemon.
- Bloating vs. Baby Bump: Most of the belly growth at this stage is from gas, not the baby!
- Mild Stretching Sensations: You may feel pulling sensations in your lower abdomen — these are usually harmless.
When Will You Show?
According to Mayo Clinic, first-time moms usually start showing around 12–16 weeks, while second pregnancies may show earlier.
