Where did you feel the cramping when pregnant?

Im feeling slight cramping from my pelvic bone on both sides, but on my right side it goes about 3/4 of the way up my stomach.... im not positive im pregnant but im pretty sure because i have all the symptoms.but im just curious if this is normal....sometimes i feel little twinges of pain hit right in the cente of my stomache... not painful just kind of uncomfortable... If I am indeed preggers, is this normal? I meanis this a symptom as well or should I ask the doctor if something is wrong with me... Im not even late for my period yet.. its due on monday the 19th....took a test last weekend and it was negative but my doctor told me to wait til Im actually late for my period because it might not be showing up yet.. iive been feeling funny for about 2 weeks now..
