Spotting 8 days after missed period

Alexandra

Expected my period on the 24th of May. Started spotting on July 1st. Very light not enough to fill panty liner. Lasted 3 days now I only notice a couple spots when I wipe. Having some pelvic soreness as well. Could this have been AF? On May 20th I did have some spotting but just for that day. I’ve taken 3 pregnancy tests and they’ve come out negative. Has anyone had this happen and came out pregnant?
