Its too early to tell for sure. My sac was not only deformed but they told me it was deflating which was a sign of the pregnancy "going backward" not forward. My placenta was half way ripped off my uterine wall, my HCG levels were supposidly low and there was no fetal pole or embryo. I was 5-6 weeks but they insisted on making usbelieve I must be 9 weeks. I planned my pregnancy literally down to the hour so I knew better. However given that information after u/s and the profuse bleeding I was having I was sent home with a pain killer rx and told to wait to pass my deformed sac as a miscarriage. I am sitting here 24 weeks pregnant! Anything is possible, my body totally repaired itself, the sac stayed sort of "deformed" and my son grew and is thriving inside me. Tell your friend not to go with this news as fact yet, it is way too early.
