confused!

Samantha
I'm currently 9dpo. I've been having very sore nipples which have been more intense than I'm used to. My boobs seem bigger and I've been having very light cramps.  On Tuesday I wiped and found a very light pink color...and that was it. So I thought it was IB. Wednesday was in the clear. This morning I wipe and there's a rusty color...not much though. An hour later and there's nothing.   I don't know what to believe anymore!! I hope it's not AF. A nice person on here told me that even if it is AF, it's too soon to have and can impact the implantation timing. I went off birth control in May and my cycle has been pretty regular with the exception of this month in which it came a week early and lasted 12 days. 
I don't even know what I'm asking. I'm just confused and need to vent! :(
