Help!!

TTC baby #2 I was suppose to get my period Feb 13 never came and feb 15 I started to “spot” brownish red blood it was only when I wiped follow day it was more reddish so I thought my period was coming in but today Feb 17 when I wipe I see brownish red blood again and I haven’t really had a normal period I put a pad on and it’s pretty much clean. I didn’t take a pregnancy test yet because I haven’t had any pregnancy symptoms and I thought my period was coming in yesterday Feb 16 since the blood looked more reddish what could it be this is a first

Test came up negative❗️❗️
