Period?

So I'm pretty sure my period came early but I just want opinions because I guess it could be spotting. I just don't want to input or wrong in glow and mess things up. 
Anyways so this morning when I wiped there was like brownish blood kind of like what it looks like at the end of a period. I put a tampon in figuring it was probably the start of a period. 2 hours later when I changed it though there was barely anything there.
