Hi all, had an early scan last week. I thought I was 6w exactly based on LMP (although my cycles are longer - more like 33 days so was expecting to be put back a few days). She could see a sac, but it was empty, and measuring 4+6. Got to go back next Tuesday.
Really really really wish I hadn't bothered going at all, as it's done the opposite of reassure me! It might be completely fine, and as I don't even know when I ovulated, those dates could be right and it's just too early to see yolk or baby. Obviously they should definitely be visible next week so will know either way.
If anyone has any stories of similar would love to hear. I can't stop googling and have convinced myself it's a blighted ovum. My pregnancy tests are still showing up extremely strong though so I am holding on to a little hope. No symptoms still, but also no bleeding or cramping.
