Subchorionic bleed

Elaine
Did anyone experience a subchorionic bleed in their first trimester? Just had my dating scan which gives me almost my exact estimated dues dates (1 day off from my dates). 
Heart beat was good 167bpm but the found a bleed to the right of the sac measuring 8.6mm. 
I've never had this before. Did it cause you any problems if you had this during your pregnancy?
