Am I too skinny for my height?

I weigh 107lbs, and I'm 5 foot 2 inches tall. I heard that I'm within "normal range" for my body m index, but if I lose 7 morelbs, I'd be consitered under weight. You can see my collar bone very well, and my ribs too....I'm Very tiny...my waist is 25 inches around, and my hips (at the biggest part) is 34 inches....from side to side (width wise) I'm 12 inches...am I TOO skinny? I'm 21 years old...I just don't feel right. I'm still in Juniors clothing. (Sizes 7-9...depending on how they're made) *yeah, "big hips" and how do I love my itty bitty love handels, or shouldn't I worry about it?
