this is TMI but I'm scared... I don't know what I ate that gave me a really bad diarrhea and this last time I went to the restroom I didn't have to go but I still feel like I do... (I don't know if I'm the only one whose anus gets a burning sensation when I have dirrhea) this hurts! and not only that, it started bleeding a little bit. should I call the Dr?? I'm just really worried since it's coming from back there, not my vagina I'm 4 weeks pp
