Brown Dischargee?

Angelica

I’m supposed to have my period in 2 days, my boyfriend & I have been trying for a baby and yesterday i had some brown discharge that was gooy and it was a little bit, then last night i had some spotting when i wiped and never came back and now i have this brown discharge again today and it’s only a little like this when i wipe, what could it be? I’m really hoping it’s a sign of pregnancy but i took a test last night and it came back negative.
