According to my conception time frame, I should be approximately 5-6 weeks pregnant but the U/S doesn't show anything but a big cloud. My beta went from 800 to 1200 in 2 days. It didn't double as it should have. The Dr said that we may have the conception dates all wrong and that we MAY BE looking at an extrememely early pregnancy but yhat she will be referring me to a specialist for a more in depth U/S don't because they just don't know what is going on. Can someone please give me some advice on this, I'm about to pull my hair out in frustration!
