What are the symptoms of pregnancy after first week?

1. Missed period: The most common early sign of pregnancy is a missed period. If you are sexually active and your period is more than a week late, you should take a pregnancy test.

2. Breast tenderness: Your breasts may become tender and swollen as early as the first week of pregnancy. This is caused by the rising levels of hormones, particularly estrogen and progesterone.

3. Fatigue: Extreme fatigue is a common symptom of early pregnancy. This is thought to be caused by the increase in progesterone levels, which can make you feel sleepy.

4. Nausea and vomiting: Nausea and vomiting, commonly known as morning sickness, can start as early as the first week of pregnancy. They tend to peak between 8 and 12 weeks, then gradually decline. However, some women experience morning sickness throughout their pregnancy.

5. Bloating: You may experience bloating in the early stages of pregnancy. This is caused by the rising levels of progesterone, which can relax the muscles of the digestive tract and slow down digestion.

6. Mood swings: Early pregnancy can also cause mood swings due to the hormonal changes that are taking place. You may feel happy and excited one moment, then tearful and irritable the next.

7. Increased urination: You may find that you need to urinate more frequently in the first few weeks of pregnancy. This is caused by the increase in blood flow to the kidneys and the expanding uterus putting pressure on your bladder.

8. Cramping: Mild cramping in the lower abdomen is common in early pregnancy. This is usually caused by the growing uterus stretching the ligaments that support it.

9. Spotting: Some women experience light spotting or bleeding in the early stages of pregnancy. This is known as implantation bleeding and occurs when the fertilized egg implants itself in the uterine wall. Implantation bleeding is usually lighter than a regular period and only lasts for a few days.

10. Back pain: Lower back pain can be a symptom of early pregnancy. This is thought to be caused by the shift in the center of gravity as the uterus begins to enlarge.
