can I be pregnant?

hey ! so im currently 11 days late. when I was suppose to start my period i was spotting but not enough to use a pad. (3 days) I would only see blood when I wiped. My teeth hurted for 2 days (idk if that helps)and ive seen an increase of discharge but on sunday night i took a pregnancy test and came out negative ): I had unprotected sex when i was ovulating . should i wait longer to take another test or am i just not pregnant? (not stressed over it either)
