• Missed menstrual period(s)
• Fatigue
• Breast enlargement or breast discomfort (tenderness)
• Abdominal distention

The health care provider will perform an examination, which may reveal:

• an enlarged uterus -- the top of the uterus (the fundus) may be felt by touch
• a bluish or purple coloration of the vaginal walls and cervix
• softening of the cervix
• weight changes (usually weight gain, although weight loss could occur if nausea and vomiting are significant).
• increased size of the abdomen

Tests include:

• A positive urine and/or serum HCG (pregnancy test)
• A pregnancy ultrasound to confirm or check accurate dates for pregnancy

Pregnancy may also alter the results of numerous laboratory tests.
