I'm Nervous to sit there and think the worst and not have someone able to answer my questions! Thanks :) I am having a dating ultrasound done next week (my guess is between 6w5d and 7w5d). Not to upset you but at 6-7 weeks there really isn't much to have pointed out!I am In toronto and I know that the technicians can't really tell you anything.
