more waiting and watching

We had our u/s today and baby is alive and measuring well.  However, we have a small pocket of fluid (blood) down low in the uterus.  My RE seemed unconcerned and said that it was small and not near the baby, but this is exactly how my last miscarriage started.  I am burnt out.  I am tired of worrying.  I am tired of watching babies grow and die.  I can't do this again.  We have another u/s next Thursday and hopefully the hematoma will be smaller or if the baby is going to die, it will do so soon.  :(
