Holy crap!! Is this what I think it is?!

Ok, so I'm due for my period on Saturday; I'm very regular. I've been feeling tired, nauseated, hungry, cranky, boobs hurt...! I have also had cramping. Today my bbt DROPPED & I googled it because I was sure I wasn't pregnant & google said it could mean implantation occurred! Then today I went to the bathroom and I'm bleeding! Light pink and not a ton...! What is this bleeding 5 days sooner than my period? Could it be implantation?! Help!!! Omgggg!!!
