Pregnancy begins when a fertilized egg implants in the uterus, leading to a series of physical and hormonal changes. Early signs of pregnancy can vary but often include the following:

Common Early Signs of Pregnancy

• Missed period: The most obvious and early sign for women with regular cycles
• Nausea or morning sickness: Feeling queasy or vomiting, usually starting around 6 weeks
• Breast changes: Tenderness, swelling, or darkening of the areolas
• Fatigue: Feeling unusually tired due to hormonal changes
• Frequent urination: Caused by increased blood flow and pressure on the bladder
• Mood swings: Emotional fluctuations due to hormone shifts
• Food aversions or cravings: Sudden dislike or strong desire for certain foods
• Light spotting or implantation bleeding: Small amounts of bleeding or spotting around the time of the expected period; usually lighter and shorter than a normal period
• Bloating and mild cramping: Due to hormonal changes affecting digestion
• Constipation: Slowed digestion during early pregnancy
• Heightened sense of smell: Increased sensitivity to odors

Additional Signs to Know

• Basal body temperature rise: A slight, sustained increase after ovulation can indicate pregnancy
• Cervical changes: The cervix becomes softer, higher, and more closed in early pregnancy
• Headaches and dizziness: Caused by hormonal changes and increased blood volume
• Increased vaginal discharge: Thin, milky discharge (leukorrhea) is common and normal
• Heartburn or indigestion: Hormonal relaxation of stomach valves may cause reflux
• Leg cramps: May occur in early or later stages of pregnancy
• Positive blood test: Detects pregnancy earlier and more accurately than urine tests

Other Possible Signs

• Changes in taste or metallic taste: Some women notice altered taste sensations
• Nasal congestion or nosebleeds: Hormonal swelling of mucous membranes can cause this
• Increased basal heart rate: Slightly elevated resting heart rate is common
• Mood changes: Beyond mood swings, symptoms of anxiety or depression may appear
• Breast colostrum: Some women notice early yellowish nipple discharge (colostrum) as pregnancy progresses
• Weight gain: Early subtle weight gain or bloating can occur
• Sleep disturbances: Hormonal changes can affect sleep quality and patterns
• Frequent headaches: Hormonal fluctuations can trigger headaches or migraines

When to Take a Pregnancy Test

• If you miss your period and suspect pregnancy, use a home pregnancy test for confirmation.
• For best results, test with the first morning urine when hCG hormone concentration is highest.
• A blood test at a doctor’s office can confirm pregnancy sooner and with greater accuracy.

When to See a Doctor

• Confirm pregnancy with a healthcare provider
• Begin prenatal care to monitor your health and your baby’s development
