spotting?or something else???

hi there, I've been off my period for about a week now, today when I went to the toilet I wiped and there was small amount of blood on the toilet paper? I've never had this before? I also have unprotected sex with my boyfriend , we have been together for 8 and a half years and always have unprotected sex because we really want a baby. Could this be a sign ?? spotting, I also have had diarrhea today and was nearly vomitting 🤢 is it just me?
