Feeling warm during pregnancy is common, but a true fever could signal an infection¹, and untreated infections are a leading cause of preterm birth². Getting care quickly helps protect both you and your baby.
How to Know if You Have This
Use a thermometer to check your temperature if you feel sick or warm or have chills.
A fever is usually defined as 100°F (37.8°C) or higher when measured orally¹.
Feeling flushed or warm alone does not always mean you have a fever—always confirm with a thermometer.
When it's Urgent
You have a fever of 100°F or higher.
