Implantation or period

Hey ladies i need some help and hopefully some advice from someone who has experienced this. My period is supposed to be due 2mrw (Saturday), well Wednesday i wiped and had pink discharge on the toilet paper, i was thinking it was my period so i put on a pad. Nothing at all on the pad all day long but everytime i went to pee there would be light brown on the toilet paper when i would wipe but nothing mixed in with pee like when AF shows? I have wore a pantyliner since Wednesday, and nothing at all until i go pee and i see light brown only when i wipe?? Has anyone had an experience like this and ended in a BFP?? Im so confused!! Please give any advice u can and thank u all in advance!!♡😊
