Symtoms too early?

Katie

Hey girls of course it's only been 5 days since the deed and ovulation and I'm going crazy waiting for the "5 days before your missed period" mark to take a test..😳😳 but I SWEAR I'm having some symtoms as of today..i googled and i read that implantation could happen as early as 5 days or as late as 12...at 5 dpo I'm already having implantation symtoms like weird tugging mini cramps one side and also the fact that my nipples are KILLING me! They're burning from them rubbing under my soft robe and boots are pretty sensitive...I guess I'm asking if anyone has ever gone through implantation so early?? Or what IS the earliest you have..?
