Sac: An empty sac is probably not a viable pregnancy but wait and see what your next ultrasound shows

Possible: Could be twins, but not later implantation. Either they did not see the second sac right away because of the early gestation, or they misinterpreted the extra embryonic coelom as a second sac.
