does anyone get spotting before their period?

Does anyone else get spotting before their period is due? Mine is due in a couple days and since last Thursday (4 days now) I've been spotting very light brown and pink discharge. I am not on birth control. I do have very painful and irregular periods though, if that helps. Just wondering if this is normal. I tend to get a little crazy when new things happen to me & think the worst! Also I am NOT pregnant.
