Frer 6 days sooner vs frer rapid results

Megan

Hello I got a really really faint line on a frer 6 days sooner yesterday morning and today I tested with the frer rapid results today at 12 dpo in the evening, I did drink Starbucks before and maybe my pee Could’ve been diluted but I couldn’t wait and it came back negative now I’m feeling like I’m out. Had this happened to anyone before?? I’m 12 dpo and due for AF in 2 days.
