Short and light periods?

I've always had light and short periods. My cycles last anywhere from 30-32 days. I ovulate on the 19th and 20th day of my cycle. I have also had an HSG and ultrasound with solution to make sure everything is fine and it was. We haven't been TTC for long at all, but I just want to make sure that me having light and short periods wouldn't be means for concern. My doc doesn't seem to be worried about it, but ya never know.
