Had first US last week. The size of the gestational sac measured more like 5 wks instead of the 7 wks from my LMP. too early to detect the heart beat so I go back in 2 wks. Worried because I've already miscarried. Also started noticing less morning sickness since then. Could they be wrong about the size of baby? Could I be having another miscarriage?
