More bad news :( has anyone experienced this before?

UmmAisha
Went for an ultrasound today and thank God they found baby this time and heart beat all looking perfect. However she also found a bleed outside of the sack.
Yesterday i had a pretty bad cramp in my lower left side. The doctor told me to not tell anyone im pregnancy yet as it could go either way and i should mentally prepare for miscarriage? She also gave me some hormones to take to support the pregnancy. 
I havent bled yet but im now expecting to. What are my chances? 😞
