Help?!

period is 14 days late I had brown spotting a tiny bit 3 days ago thought it was AF started bought some pregnancy tests and tested with a faint positive but still was kinda stuck because if I’m this late my test should be darker than it is .. I have been cramping for a couple days now without any bleeding or spotting just the brown discharge once now this today when I wipe I’m confused

I wiped twice and 1st time this came out

2nd it was more brown then nothing else tissue is dry
