ok take a breather, the doctor will not be able to know how your HCG level match up with your baby until he is able to give you a sonogram that matches your HCG Levels. If your sono shows your baby being at lets say "10 weeks, then your blood should match this but you have to have an actual image beyond the black spot" That's why he was waiting for june but since your levels are climbing really high he suspects that there should be a image to match that at this point. I hope that helps you some. Maybe your older than you think in gestation.
I do know that high levels of Hcg can mean a multiple pregnancy.... Here is a chart that I always reccomend to people... Hope this helps.
