Due May 20th Subchrorionic hemorrhage, anyone else had similar circumstance?

Hi everyone!
I went to the doctors last week for some light spotting and received a viability ultrasound. Baby looked great and had strong heartbeat of 133 at 6 weeks 3 days. I have still had slight spotting and when I went to my doctor today and they did an ultrasound again they found a small subchrorionic hemmorhage. Doctor and ultra sound tech didn't seem worried and said it should absorb itself and isn't by placenta so it's an idea location to have one. 
This is my 4th pregnancy, 3rd baby (one ended in an early miscarriage) but have never experienced this before.  Any other mamas had this before or have it now? Just trying not to stress.
Thanks!
