Measuring two weeks behind

Lauren

I wanted to see if anyone has some success stories.... I’m 8 weeks based on LMP but had a dating US today that showed me being only 6 weeks. The US tech and MD seemed concerned and said that it was 50/50 which way this could go at this point and that he’s seen similar situations end in a normal pregnancy and others end in miscarriage. My periods are very regular and I had a positive test exactly 4 weeks ago today so I’m sure on the dates. Any thoughts? I’m in shock, don’t know where to go from here. I’m going back for repeat US and HCG levels next week....
