ok seriously need advice ladies.

I posted yesterday about spotting when I wiped some very light pink blood 2 days before missed period it happens a couple more times yesterday nothing ever made it to a pad. Now the this morning I wiped and the blood looks old it's deeper in color not red has a brownish tint to it, still nothing on pad just if I go to the bathroom and wipe this isn't normal for me my periods are usually pretty by the book a normal flow that starts gets heavier then lighter then gone.. has anyone experienced this? I feel silly buying and taking a pregnancy test while I'm bleeding. I have know one to talk to so I'm anxiously waiting your comments! And I have not tested at all this month just so u have all the facts!
