Spotting for 7 days

So my periods late, by like 2 days and I've been having super light spotting since last Thursday. Pink and brown in color, havent even needed a panty liner or anything it's so light, its only lasted a few hours out of each day. I took 2 test when the spotting started, cause I started lactating again, havent nursed my baby in 4 months, and got what I thought were 2 super faint lines, so I'm wondering if it's worth taking a test again, does spotting that long count as a period?
