Not normal for me...

Dyani
My last period was not normal at all I had a light 2 day period then I spotted for 2 days after that. which isn't normal at all considering that my last two periods were heavy and 4 days long... Any ideas? Or advice? My period also was a day late my cycles are changing I don't know if that's normal or not I talked to my OB she couldn't give me any answers.
