Can a bump in a stomach mean you are pregnant within 3 weeks after sex?

Weight gain during pregnancy normally doesn't start till around your fourth month, when the baby is big enough to push against the wall of your stomach. Three weeks into a pregnancy the baby isn't even the size of a bean, let alone big enought to push on the stomach. The bump could be many things, it is best to get checked by a doctor and explain your concerns.
