Very Early Pregnancy Symptom

Symptom Details

Heartburn is typically associated with later pregnancy as the baby grows and takes up more and more space in the abdominal cavity, but the hormones produced in early pregnancy can also cause heartburn. Progesterone, which relaxes the smooth muscles of the uterus, may also relax the valve between the esophagus and the stomach, allowing stomach acid to travel back up to the esophagus, causing heartburn even in early pregnancy.

Comparison Chart

The chart below shows a comparison between the number of times this symptom was experienced by pregnant vs non-pregnant women.

**NOTE: Data for 15-21 dpo tends to be lower than expected as many women stop tracking symptoms after a positive pregnancy test.
