Lost!

Karina • Super excited baby #2 is on its way due sep.2015
So I started to bleed Monday night 
​:( took a prego test cause I was having a lot of pain with my morning urine said I was pregnant rushed to the er ultra sound showed nothing and blood test didn't ether 
​Took a pregnancy test again tofay said positve  
​Doc said might be really early that ultra sound won't see until 6 weeks so very confused don't know if I should be happy or scared
