A little advice.

Sorry for the tmi. I am 9 dpo. My af is due 3/28. My cycles are 34 days. Today when I wiped I have had some brownish discharge on the tp. All day it has happened. Part of me thinks it could be implantation bleeding the other part of me thinks it my period starting early. What are you ladies opions? Implantation bleeding or early Af. Yes I'm ttc.
