Embryonic sac but no baby

I am 8 weeks and had my first ultrasound yesterday. My doctor found an embryonic sac but it was empty. 😔 She told me to come back for another ultrasound in 2 weeks. She was very sad and said the chances are low that everything is ok but just wants to make sure. I know this is bad, but I don't feel like the baby is there and would rather take misoprostol now, than prolong this. Is there any reason to have hope? I want to be realisitic here. I would rather have closure than drawing out the emotional pain for another two weeks. I am going to talk to my doctor on Monday about my concerns and if it is worth the wait.
