A little TMI. Sorry. Confused!

Could I possibly be getting AF early??? I'm only 7dpo & I've had creamy cm for the last 4 days since 4dpo. I wipe today & there's a bit of pink in it! I NEVER get AF this early & I only spot at most a day or 2 before AF comes. I've been tracking AF since around 2002ish & I've always had 36-38 cycles with a few variances with cycles changes every few months. The only time I've ever had AF on cd 20something is when I was on the pill in 2010. I did have pink spotting when I was pregnant with the twins. But who knows. I just find it very weird. Could I be getting AF this soon? I'm only on cd22.
