Ovulation spotting?

Sorry if this is TMI... but on CD 11 and 12 I went to the restroom and had light pink blood when I wiped on CD 11 and then light brown on CD 12... could this be ovulation spotting? I’ve never had this before! I’m not sure if it’s just annoying random bleeding or ovulation spotting. And no... I’m not doing OPKs. So I’m not 100% sure when I’m supposed to ovulate. So I’m not sure if I ovulated early. Just wondering if anyone else has experienced this or could give me further information!

Thank you in advance!
