So confused!!!! Please help!!

So I had a chemical pregnancy last month...I started bleeding on 8/16. Bleeding. Ended on 8/21. On CD 8 opk came back as high fertility so we BDed. I though in my mind that it was too early to be fertile in the cycle but maybe it had something to do with the MC. I still have yet to have Peak result. Anyway. 3 days ago I had some moderate spotting 1x and then nothing until just now. It was red blood mixed with fertile CM. Really slippery but with red in it. I have NEVER EVER spotted EVER. Could it be implantation bleeding from the high fertility on CD8? (About 11days ago) or could my cycle not be back to normal since the MC? What do you all think???
