What is the most common sign of pregnancy?

The most common sign of pregnancy is missing a period. When you are pregnant, your body produces hormones that prevent ovulation from occurring. This means that you will not shed the lining of your uterus, which is what causes your period.

Other common signs of pregnancy include:

* Fatigue

* Nausea and vomiting

* Breast tenderness

* Frequent urination

* Bloating

* Mood swings

* Constipation

If you are experiencing any of these symptoms, it is important to see a doctor to confirm whether or not you are pregnant.
