woke spotting

next AF isnt for 12 days. and i woke up spotting !!!! ONLY NOTICED WHEN I WILPED

i found my raw egg white CM on monday so <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> was slightly off. is this possible for implantation already ???? this is so crazy to me as we hardly got a chance to BD this time ive never experienced implantation before.
