Week 6 · First Trimestermoderate
Heartburn & Acid Reflux at 6 Weeks Pregnant
Heartburn affects up to 80% of pregnant women, particularly in the second and third trimesters. It occurs when stomach acid backs up into the esophagus.
👶 What's Happening at Week 6
Your baby is now the size of a lentil.
- Facial features begin forming — dark spots where eyes will be, openings for nostrils.
- The jaw, cheeks, and chin are taking shape.
- Tiny fingers and toes start to form from the limb buds.
🔬 Why You're Experiencing Heartburn & Acid Reflux at Week 6
- Progesterone relaxing the lower esophageal sphincter (the valve between stomach and esophagus)
- Growing uterus pushing stomach upward, reducing its capacity
- Slower digestion during pregnancy allowing more acid production
- Eating habits and food triggers

Frequently Asked Questions
Does heartburn mean my baby will have lots of hair?
Surprisingly, a 2006 Johns Hopkins study did find a correlation! But heartburn is caused by hormones and anatomy, not baby's hair.
Is Pepcid (famotidine) safe during pregnancy?
Most doctors consider famotidine safe during pregnancy when antacids aren't sufficient. Always consult your provider before starting any medication.
Will heartburn go away after delivery?
For most women, yes — heartburn resolves within days to weeks after delivery as hormone levels normalize and the uterus shrinks.
