Period or Implantation Bleeding?

Renee

I'm 6 days late, I wiped earlier and noticed light brownish spotting but nothing on the toilet paper.

We've been trying to conceive since July 2017 with no luck so far. I took a pregnancy test Wednesday morning but. it came out negative 😞 Did I test too early? I'm not having much symptoms that I've noticed. Since period symptoms and pregnancy symptoms are very similar it's very hard to tell if it's my period coming, stress, or if I'm pregnant...
