Implantation at 12dpo? Please help ladies 😬😬😬😬

Hi guys. Not quite sure if I’m 12dpo or 13dpo... I had a LH surge on the 17th at 7pm so I’m assuming either the 18th or 19th I ovulated ... so I’m either12 or 13dpo... regardless I had light pink CM today. Not a ton - didn’t reach my underwear. But it was clearly the CM that was pink. Breasts are super super tender today. Not much other signs of AF - except slight cramping this AM about two hours before pink CM.... could it at all be possible this is implantation??
