How big is your baby?

Frequent urination

Your pregnancy will cause the uterus to swell and it will start to enlarge for the growing fetus immediately. The uterus will then apply pressure on your bladder making you feel the need for more frequent urination. Many women start to feel this symptom within a week or two after pregnancy has occurred.
