1. Missed Period: One of the most obvious signs of pregnancy is a missed menstrual period. If a woman's period is regular and she is sexually active, a missed period can be a strong indication of pregnancy. However, it's important to note that other factors, such as stress or hormonal changes, can also cause a missed period.
2. Fatigue: Feeling more tired than usual is a common early sign of pregnancy. Hormonal changes and an increase in the production of progesterone can cause feelings of fatigue and drowsiness. Pregnant women often experience a significant drop in energy levels during the early weeks of pregnancy.
3. Breast Changes: Hormonal fluctuations during pregnancy can lead to noticeable changes in the breasts. The breasts may become swollen, tender, or sensitive to touch. The areolas (the area around the nipples) may darken, and the veins in the breasts may become more prominent.
4. Nausea and Morning Sickness: Many women experience nausea, commonly referred to as morning sickness, during the early stages of pregnancy. This can occur at any time of the day and may be accompanied by vomiting. While it's called morning sickness, it can happen throughout the day. The exact cause of morning sickness is not fully understood, but hormonal changes are believed to play a role.
5. Frequent Urination: Pregnant women may experience an increased need to urinate, even in the early weeks of pregnancy. This is due to hormonal changes that lead to increased blood flow to the kidneys and increased urine production. Additionally, the growing uterus can put pressure on the bladder, leading to more frequent trips to the bathroom.
6. Changes in Appetite and Food Cravings: Some women may notice changes in their appetite and food preferences during early pregnancy. They may experience sudden cravings for certain foods or aversions to foods they once enjoyed. These changes are thought to be influenced by hormonal shifts and can vary from person to person.
