Light brown spotting for 8 days....help!

kristi

I had sex with this guy I’m seeing, last Saturday. Ever since, like that night, I’ve had light brown spotting. My period isn’t due for another 3 days and when we had sex it was 2 days after my fertile window. I have to wear a liner everyday. It’s usually brown with some pink and I could wear only one liner a day and I’d be fine. Any ideas? I’ve googled it and so many things came up and I got freaked out. pregnancy, std, hurt my cervix, etc etc.
