First ultrasound...didn’t go as expected..

Colleen

I had spotting last Thursday, so my doctor had me get blood work and he did an ultra sound. My HCG levels he said were good, but when they did he US, he said everything was there (yolk sac, etc...) except the baby. He said my dates may be off, but they have me going to the hospital on tuesday for another ultra sound... nervous. My LMP was September 13th, but my cycle was 36 days preciously. Anyone else have this happen?
