How to Detect Early Pregnancy

Pregnancy is a time when a woman's body undergoes many changes. From the first trimester, your body will show signs indicating that you're pregnant. The list below explains some of the most common symptoms women experience early in their pregnancies. If you have recently begun experiencing several of the symptoms listed, make an appointment to see your doctor.

  • Missed period: One of the earliest indicators of pregnancy is a missed period. Because the egg is fertilized, it's not shed through the uterus and a pregnant woman doesn't get her period [source: American Academy of Family Physicians].
  • Fatigue: Because hormone levels rise during pregnancy, many women experience a loss of energy and a strong sense of fatigue [source: Mayo Clinic].
  • Breast swelling and tenderness: Many women describe having tender breasts during early pregnancy. This is similar to the tenderness some women experience before a menstrual cycle [source: Stoppler].
  • Morning Sickness: The influx of hormones causes nausea. Although the symptom is most common in the morning, some women experience nausea and vomiting throughout the day [source: American Academy of Family Physicians].
  • Aversions or cravings for specific foods: Your body reacts drastically to the changes in hormones levels. Many of the foods that you eat every day are nauseating, while you may suddenly crave other foods [source: Mayo Clinic].
  • Frequent urination: Many women need to urinate more often, especially throughout the night, early in their pregnancies. The body's increased production of the hormone human chorionic gonadotropin (hCG) stimulates urination [source: Stoppler].
  • Raised basal body temperature: The basal body temperature is your oral temperature after you wake up but before you get out of bed. An increase in your basal body temperature for longer than two weeks may mean that you're pregnant [source: Mayo Clinic].
