Bloating

Bloating is another early sign of pregnancy. It may be hard to tell the difference between premenstrual bloating and pregnancy bloating as PMS and pregnancy symptoms can feel remarkably similar. However, pregnancy symptoms are often more exaggerated than typical PMS symptoms. Bloating, like other symptoms in early pregnancy, is caused by hormonal changes. As your progesterone and estrogen levels rise, the lining of your uterus thickens, making you feel more bloated. Hormonal changes also cause your digestive system to slow down and this can cause bloating as well.
