Implantation bleeding?

Hi all, had a question and wanted some input/opinions, first let me share the story lol. Hubby and I will be TTC however, we really want to get pregnant on the next cycle so that our baby will be born in July so we have been using condoms for the most part. So, I began ovulating Oct 2nd (last Friday), we were intimate that night and used a condom, however we believe it broke and we didnt discover this until after the deed was done lol. The following night, Oct 3rd, I was checking my CM because I am tracking it, and there was a tiny amount of pink blood present. Could this be implantation bleeding? I had implantation bleeding with my second child, I am just hoping this is not it. We had special plans for when we try to conceive next month because we already have two boys and we really want a girl this time lol! Any input/experiences would be helpful, thank you
