How to get rid of lower stomach fat?

Okay so i have little to no fat on my stomach except for right under my belly button. So basically my stomach is all toned then just out of nowhere at the bottom of my stomach is a bulge of fat. It's not big, but since im 5'4 and 109lbs it's pretty noticable. It totally prevents me from wearing the chothes i want. If that one freakin bulge was gone i would be able to wear whatever i want. How can I get rid of it????? D:

Btw i go to the gym every other day and do 35 minutes on the cross trainer and crunches on a machine thingyy.
