At two weeks it is still so tiny, can barely be seen with the naked eye. Let alone having a baby bump. Mind you, a fetus doubles in size almost everyday so it will be no time at all before you are showing, usually the second month. If you feel a flutter, like holding a goldfish in your hand, the baby is beginning to be big enough for you to feel. It is really cool when this happens. Others won't feel it, but you will. 2 weeks is nothing. It is almost as if there is nothing there. It takes more time for you to feel it inside and a lot more time for others to feel it as well
