MENS / SPOTTING OR DISCHARGE?

16 days past ovulation. 1 day late according kay flo and 2 days late according kay my tracker petal. Nag pt na ako 3 days before and 2 days before expected period pero negative. Then ayan lang morning may discharge ako na ganito. Mens na po kaya? Salamat sa mga tulong. PS. Sorry di kasi ako nag uundies pag matutulog, short shorts lang. Thanks.
