I am about 2 weeks late on my period I have had terrible diherrah my stomach makes hungry noises a lot. And I have been eating like crazy. Normally when I'm getting mine I'm very hungry so that's not atypical for me but I'm pretty regular on my cycle. I have taken several pregnancy tests r othey say negative so I'm wondering what else could be the problem. I also want to add I ahave a 9 yrold son and have been pregnant before. I'm only 31
