Is this IBS or something i ate?

Yesterday i ate some eggs wrapped in bacon, last night i ate some casserole, this morning i had diarrhea, then i went again a couple hours later and it wasn't diarrhea, then a few hours later i went again and it was a mixture of diarrhea and soft stool. It seems acidy too as its making my bottom raw to the point where my bottom is bleeding a little not from the anus but the butt crack itself. Sorry to be so explicit i know its gross I'm just wondering if it may have been from something i are or possibly ibs.
