What is this!?! 😷

Sorry for the tmi but I would like some input please. I had my daughter in Feburary and I only breast feed once a day. I had my first period in may and missed June then on July first I had very light spotting for one day only and didn't get my period, I took a pregnancy test and it was negative. Anyway, today is july24th and I wiped and this was on the tp, is this old blood? Do u think my period will start now? I'm just confused lol
