Is it normal to feel pressure when you are only 2 weeks pregnant?

You will find that this "pressure" is not your uterus, but your bowel. It is probably bloating. Pregnancy causes your digestive system to slow down so that your body can absorb more from the food you eat to support the baby. This is why you get constipated when you are pregnant. Your body knows that it is pregnant and has told your bowel to slow causing pressure in your lower abdomen. Try to eat a lot of bran products to get your bowel moving.
