Slight bleed a week an a half before period

Today when I woke up I felt totally tired and drained.. I got up around 5 and I felt great later in the night my husband decided to go to bed and I felt frisky so we had our play time.. He made sure I had my orgasm and we were still going at it so he could finish, but he stopped because he noticed blood.. Anyways my question is my period is not for a week an a few days and I'm bleeding slightly is that a good thing if bad? P.s. We had sex Friday and he came could it be egg implantation?
