unusual period?

Lj

I have experienced so many pregnancy symptoms that I had with my daughter, but two days after AF if was due I started spotting. I have remained spotting from Saturday night till still this day (thursday 10/5). My period are always gushers, so this has me thrown off a bit. I haven't tested since Tuesday and it was still negative and my OB did not want to give me a blood test at this time.... so ladies what is your experience with light periods?
