6 Weeks Pregnant: Symptoms & Baby Size

You're halfway through your first trimester! Here is what's happening with you and your baby.

At 6 weeks pregnant, things are getting real. Your clothes might feel a bit snug due to bloating, and you're likely feeling the full force of pregnancy hormones. In 2026, we have more ways than ever to track this journey, but the excitement of these early weeks remains the same.

How Big is Your Baby at 6 Weeks?

Your baby is currently the size of a sweet pea or a pomegranate seed.

Even though they are tiny (about 0.25 inches long), incredible things are happening:

  • The Heartbeat: Your baby's heart is beating at about 100 to 160 times per minute—nearly double your own rate!
  • Facial Features: Tiny dark spots are forming where the eyes and nostrils will be.
  • The "Tail": Your baby currently has a small tail (the end of the spinal cord), which will disappear by the end of the first trimester.

Common 6-Week Symptoms

The hCG hormone is rising rapidly now, which can lead to a variety of "fun" symptoms:

  • Morning Sickness: Not just for mornings! You may feel queasy throughout the day.
  • Sore Breasts: Your body is already preparing for breastfeeding.
  • Frequent Urination: Your kidneys are working harder to process waste, and your uterus is starting to press on your bladder.
  • Extreme Fatigue: Growing a human is exhausting. It’s okay to nap!

What to Do This Week

1. Schedule Your First Prenatal Visit: Most doctors want to see you between week 8 and week 12, but call now to get on the books.
2. Check Your Skincare: Some ingredients like Retinol should be avoided during pregnancy.
3. Stay Hydrated: Drinking water can actually help reduce the bloating and nausea you may be feeling.
