HI,

I reckon that you should go an get it checked out. I did get some pains early on, but they were not sharp, more like aches that came and went (like period pain). these pains i was told were as a result of ligaments stretching etc etc, so hopefully it is just that. Some people dot feel anything this early but i certianly did and i did think that it was just my period coming as it was so early one and i really wasnt pregnant.
Hopefully it is nothing, but you are better to go and make sure that there is nothing going on, if nothing else but peice of mind...
Goodluck
