TTC and needing advice about light pink blood when I wiped after peeing...

Ok my last day of my peroid was August 3rd.. Acording to glow im supposed to ovulate tomorrow August 12th annnd my birthday is tomorrow ill be 26, lol great day to ovulate haha

Anyway yesterday I slight pink blood when I wiped after I peed... We had sex on the 3rd, the 8th and lastnight... What could the spottong be? Of cource my silly mind thinks it could be inplatation bleeding but im shure that is waaaayyyy to soon. But we also had sex a few days before my period..

Im just trying to figure out what the pink may be. Any advice as to what it may be?
