Pls help! spotting pink/brown ever since ovulation...why???help!!!? - cervix befor period

Me and my DH had sex 2 days before ovulation, EI (day of ovulation, the cervix was very high, smooth and) Mucus protein. This is not always very very very much for good, but my day of ovulation cervical mucus is stained with brown blood when washing, and went, but now, from time to time, a pink marble when it is cleaned and (now I'm 3 days past ovulation) ... I know that implantation can occur so quickly, but why am I so colorful ovulation? I could check my cervix for fertility, because of that many days? pls help!
