Help from anyone whos had implanation bleeding or whos educated on it... Better than me;)

Sooo... Im freaking out! Today is 12 dpo. I found a very light pink in my cm. Like literally, just now! But, sad thing is AF is due, according to Glow, in two days... Ive got quite a bit of cm mixed with light pink. What ta ladies think? Could be implamation? Or should i give up, call it a day and give a big bird finger to Aunt Flo for crushing my baby dreams this month?
