Oh and around 3 to 4 weeks ago I had a big fall where I hit my left hip (just above the hip). For a week or two I felt pain when sneezing and laughing...could it be related to that?
I suggest you see your doctor or go to the ER ASAP. It's not good if you only had 2 bowel movements in 2 weeks! You need to be checked now
Hopefully you have already gone to a doctor. It sounds like you have constipation, a blockage, or a hernia, as the area below your belly button is the intestines. It could also be a cyst on a pelvic organ interfering with intestinal functions.
The light stool color is usually a sign of reduced bile. That could be caused by a blockage in the biliary tree that feeds bile from the liver to the gallbladder, enzymes from the pancreas, and both into the small intestine.
If you haven't already, go to a doctor as soon as possible!
hard abdomen is not a good sign
