I went to the doctor today and baby is measuring 6 weeks exactly and we saw his or her heart flickering. The doctor came in afterwards and let us know that my HCG is rising, but not as much as he'd like to see and that I need to have a repeat ultrasound in a week. He says it's possible to have a healthy pregnancy, but it's also possible I will miscarry. I did not ask him my exact levels. Any personal stories? I want to be hopeful, but it's hard.
