🤷‍♀️ confused

According to glow I am suppose to be ovulating now but I've been getting negativite ovulation tests for the last few days and been testing 2 sometimes even 3 times a day. Also yesterday and today I have had some spotting but had been red blood. My period is not due for another 13 days. Could this be implantation bleeding or my period coming sooner than expected? Also took a pregnancy test this morning and negative 👎🏽
