First pregnancy... I took a preg test that came out positive on 11/19. I went to the doctor on 11/20 and they tested positive as well... off of my period calculations I'm supposed to be 4wks pregnant with a due date of 7/28/16. The doc just called me back today to tell me that my blood test came back saying I was only 2 wks pregnant. I am planning on going IN to talk to the doctor tomorrow in the morning, but my branding is racing a million miles an hour.. What does this mean? How far along am I and is there possibly something wrong? I have never heard of someone testing positive so early and I'm not sure what's going on.. any advise?
