Implantation bleeding or period?

Megan

For the past 3 days I have spotted a tiny bit of blood just once in that day.

I’m supposed to start my period in 3 days and I started spotting 6 days early. I had unprotected sex 2 1/2 weeks ago during ovulation.

Normally before I start my period I might spot the day of and then later that night I’ll have my normal heavy bleeding period.

But this started out the first day as light pinkish red spotting then the next day it was brownish and now it’s rusty brown dark almost black.

I took a test the first day I noticed the pinkish red spotting and the test was negative.

Do you think this is my period or implantation bleeding?

I guess time will tell.
