I Have Discovered That I Have Several Bruises On My

I have discovered that I have several bruises on my body, my legs, arms, breasts, stomach. There are no reasons for the bruises that I know of. I do bruise easily when I hit something, but not in the places that the bruises are showing up. Should I be concerned about this? Could it be symptoms of new medications that I am taking? I am female, 58 years old. thank you, Paula Myers
