TMI-ish early pregnancy symptoms?

I'm about 5dpo and my gums bled this morning when I brushed my teeth. On top of that, my bowel movements have been unusual, though I haven't eaten anything strange. I was feeling constipated this morning then I had this rush of nausea and then diarrhea. I KNOW I'm being crazy..... But do any of these things indicate that I could be pregnant? Anyone have the same symptoms?
