Why am I crapping every 2 hours?

I had real diarrhea while my period hit, which happens at least once a year for me. It cleared up for a few days, and came back 3 days ago, but it's not at all watery, so I suppose technically it's not diarrhea. Anyways, I don't drink milk, caffeine or alcohol, I don't have a high fat diet, but I keep having tiny little shits every hour or 3 that are soft serve (the consistency of the feces would imply that I've been eating a lot of high fat foods). Aside from that, I'm mostly ok, I feel feverish sometimes but it goes away, I've had very little energy it feels like, and some minor abdominal pain.
