Evap? Vfl?

I took this last week the day i has light pink discharge! I could see a faint pink line. I have had all the symptoms and i thought i felt implantation take place 3 days ago. But when i test, digitals are coming back as not pregnant. I took other tests and i couldnt really even see a faint line anymore. Am i out for this month? Was the pink discharge implantation bleeding and i am just testing way too early? I dont know what my next steps are! Please comkent and give your input! Is this a evap or a vfl?? Thank you!
