1. Constipation-

As you proceed in pregnancy, your constipation problem will increase. The increased progesterone level hinders the digestive process and delays the bowel movement. To get some relief from constipation, drink a lot of water, eat fibrous food, and walk around for 30 minutes.

2. Frequent Urination-

Being pregnant takes a lot out of you. As your uterus expands, it applies pressure on your bladder, making your frequent visits to the washroom.

With a growing bump, your digestive system is also pressurized which makes your digestion slow. The pressure on the digestive system also pushes the stomach acid upwards resulting in heartburn.

During pregnancy, you gain more blood and the increased supply of blood puts pressure on tiny blood vessels inside the nose resulting in a nosebleed.
