I agree 6w is early to have a fetal pole but I'm actually either 7w5d based on LMP or 8w0d based on O so I am worried that both Saturday and today measuring the same at 6w0d. Dr said the vanishing twin is the reason there isn't a fetal pole developed yet but I'm so worried. Thinking about doing a private scan in a week and then the Ob is scanning in 2 weeks.
