Confused ! Help please😭😭

Kayla

The past three months I’ve had negative ovulation tests. Even tho this app says it’s ovulation week/day. This month 12 days after unprotected intercourse I noticed I was spotting very lightly. It only showed when I wiped. BUT this spotting also occurred durning my predicted ovulation time but both the pregnancy test and several ovulation test came back negative!! So I’m so confused 😭 is it ovulation spotting or implantation bleeding. My period isn’t due until the 4 of October. This is driving me crazy !!!!!
