I don't think you need to worry (easier said that done, right?) but spotting could signal a hormone imbalance... I think it's worth a call to the doctor. They can probably just do a blood test to rule out a lot of things.
Some women are just spotters. Do you notice you have spotting after DTD? That is pretty common. It happens when the cervix gets bumped. It doesn't mean there is a thing wrong, though.
