TTC question PLEASE COMMENT

Brittany

I am currently on cycle day 12 and expected to ovulate on the 16th. My husband and I did the deed yesterday and tonight and after intercourse tonight I noticed a pinkish mucous discharge. obviously it was semen from him and blood mixed. But I am curious as to why I would be "spotting" on cycle day 12 IF I have no ovulated yet. Of course Google says "implantation bleeding and ovulation bleeding" BUT isn't it to early for all of that?
