Ovulation and sex and discharge help

Ok ladies so I ovulated on Thursday ,Friday & Saturday according to my clear blue tests. My peak ovulation was on Friday because that was when I had the LH surge so I had sex on Friday basically what happened was yesterday I had pink/brown light spotting a couple times when I sipped then gone? Is that a early sign of implantation or has anyone got any other ideas what it could be we have been ttc for over a year now 😫
