You should go to the doctor right away about your symptoms.  

On a side note, unless you want a baby, or to have chlamydia, gonorrhea or syphillis (syphilis), you might want to rethink the unprotected sex all the time thing.  All of those things are at epidemic proportions these days.

But do go to the doctor.  Your symptoms sound concerning.  And you certainly shouldn't get pregnant until you find out what's causing all this.  I'm serious.  You want to start out a pregnancy as healthy as you can be, not having diarrhea and rectal bleeding.
