Ectopic Pregnancy

BabyDust
I had to go to ER yesterday . Dr couldn't see anything in my uterus . She said I have  over 5000 HCG and she should be able to see at least the yolk. 
She said its ectopic pregnancy. I am going back to hospital tomorrow for more blood work and one more ultrasound. I am hoping for a miracle . I am hopping and praying for her to see something in my uterus . 
Any of you had ectopic pregnancy and got pregnant  after that ? What are my chances?
*****UPDATE******
MIRACLES DO HAPPENS!! They saw the baby in my uterus today and has heart beat!!!!!!!
