A normal pregnancy lasts about 40 weeks and is grouped into three trimesters.
Symptoms of early pregnancy include the absence of menstrual periods, breast changes, tiredness, nausea, mood swings, or other symptoms.
A pregnancy test measures the hormone human chorionic gonadotropin in the urine or blood.
Symptoms of late pregnancy can include heartburn, difficulty sleeping, swelling of the ankles or fingers, hemorrhoids, and mild contractions.
By the end of 37 weeks, a baby is considered full term and its organs are ready to function on their own.
As you near your due date, your baby may turn into a head-down position for birth. Most babies "present" head down.
Babies at birth typically weigh between 6 pounds 2 ounces and 9 pounds 2 ounces and are 19 to 21 inches long. Most full-term babies fall within these ranges.
