Can running cause miscarriage

5wks preg , today I help a lady who had a run away child ( she was super fast ) the mother couldnt catch up to the toddler so I ran from where I was after the child round the block, 
I'm now concerned as I have some pinkish discharge, not bleeding, not sure if this is normal?
