Confused. Pregnant, pms, or ovulating ?

Ashley

So i have always had regular cycles. About a week ago i have what i thought might of been implantation bleeding i had some white cm with a string of red blood in it. Well my period is supposed to start tomorrow. But today i have been having alot of ewcm and i took a ovulation test and it came back super close to being positive well i also took a pregnancy test and it was negative. So am i ovulating this late? Or could it be a early pregnancy sign and my hormones just arent high enough to pick up on the pregnancy test. Im so confused ive never had this before. And my opks dont really have any second line at all unless im ovulating
