Hi, I' am 8 weeks pregnant dated back to my last menstrual period, last week i noticed brown snot like discharge with mild cramping, went to get emergency intravaginal scan and the seen amniotic sac and yolk sac and said there was no heartbeat because i only measure 5 - 6 weeks and yolk sac looks strong and not to worry and come back in 2 weeks, discharge is still there and worried about miscarraige.
