Pregnancy Info HOME

I am so confused. I was 5 days late and thinking that I need to test this weekend, but then last night I had some brown spotting. This morning when I went to the bathroom I had some brown/dark red spotting so I thought period was here...I put a tampon in before work. When I got home, there was some more brown discharge on the tampon along with some red too but not nearly what I normally see with my period. Sorry if this is TMI, but I...used the toilet...and with it there was some more discharge and a little was the clotty period type blood that I'm more used to. I thought for SURE I was full on my period at that point, but now it is hours later and it is still the same. Tampon only had some brown and red on it but not even close to being full. I feel like I've had way too much bleeding to be pregnant, but at the same time it is significantly lighter than my periods usually are. They usually start off really heavy initially and then taper off. I just feel confused. I have been cramping for about 6-7 days now and waiting for period every day feeling like it was always coming but it didn't for a long time. I would be 6 days late if I hadn't "started" today.. Should I just rule this out as a weird but light period??
