👶 Baby Development

  • All vital organs are present and functioning at a basic level
  • Bones and cartilage are forming throughout the skeleton, replacing soft cartilage with harder bone
  • Baby can bend limbs at elbows and knees, moving arms and legs actively
  • Tiny fingernails and toenails begin developing at the tips of digits
  • Fine, downy hair called lanugo starts growing all over the body
  • The head is still disproportionately large, making up about half of baby's total length
  • External genitals are developing though not yet distinguishable on ultrasound

💭 Common Symptoms

  • Visible blue veins on your chest, breasts, and abdomen due to 40-50% increase in blood volume
  • Thicker, fuller hair as pregnancy hormones slow down normal hair shedding
  • Round ligament pain - sharp pains in lower abdomen as ligaments stretch to support growing uterus
  • Heartburn or acid reflux may begin as progesterone relaxes the valve between stomach and esophagus
  • Increased vaginal discharge continues as estrogen levels rise
  • Possible emotional ups and downs as first trimester nausea starts improving
  • Occasional dizzy spells from blood pressure changes

🥗 Nutrition Tips

  • Eat calcium-rich foods (1000mg daily) like yogurt, milk, cheese, kale, and fortified plant milks for baby's bone development
  • Include vitamin D sources like fortified dairy, egg yolks, and fatty fish, or take a supplement (600 IU daily)
  • Stay hydrated with 10-12 glasses of water daily to support increased blood volume
  • Eat 5-6 small meals throughout the day to prevent heartburn and maintain energy
  • Avoid lying down immediately after eating to reduce heartburn risk
  • Include magnesium-rich foods like almonds, spinach, and black beans
  • Eat foods with vitamin K like leafy greens for proper blood clotting

To-Do This Week

  • Consider first trimester screening tests (NT scan + blood work) between 11-14 weeks
  • Document your changing body with weekly photos from the same angle
  • Research birthing and childbirth education classes in your area (many start in second trimester)
  • Start planning nursery layout and color scheme if you're nesting early
  • Schedule your 12-week prenatal appointment
  • Consider purchasing a home Doppler to hear baby's heartbeat (though not necessary)
  • Look into maternity clothes as your regular clothes may be getting tight

Did You Know?

If you could peek inside your uterus, you'd see your baby swallowing amniotic fluid, kicking their legs, and even hiccupping! All these movements are strengthening muscles for life outside the womb.
