Implantation bleed or impending AF?

Could be, could be not. i also myself have had 4 positives and 5 negatives and i started getting beige like discharge last night that then turned brown and then in the morning when i woke up i had my *lovely* (not) period. Wait a bit more. I spent a fortune on stupid hpts only to get my period. Guess i can use them for next month :P have 4 left lol. just dont worry and wait and see what happens, i know its hard i was driving myself CRAZY yesterday..
