Anything can happen 😑

Pari

According to Lmp I am 8 weeks 3 days, according to today's ultrasound I am 6 weeks. no fetal pole, no heart beat. July 31, 2017 - Bhcg was 10623, August 12, 2017 - Bhcg is 17063. Doctor told me that baby growth is not seen and bhcg is very slow rising. Anything can happen, be prepared. Next ultrasound will be on August 26, 2017. Any one can tell me what is happening with me. I don't want any false hope. If anyone have any idea about this kind of situation and is it possible to have a successful pregnancy?
