text: Everybody is different.  Most pregnant women start showing at about 4 or 5 months, but some do earlier or later.  It usually isn't really obvious until about 7 months.  At 4 or 5 months, a pregnant woman can usually feel the uterus in her abdomen.  But it depends on the size of the woman and the size of the baby as to when and how much she shows.  For an overweight woman, she may not show till much later.
