Hi,

I am wondering if anyone had a scan at around 7 weeks (early scan) and the embryo was measuring a few days behind (up to a week behind) in dates? I went for my scan on Tuesday and I should have been 7w5d, but the sonographer said that the embryo was measuring a week behind. The pg sack was a good size. I've had 2 pg previously, and in both of them there was a good strong HB (scans done at around 7 weeks) but this time I saw what was a beginning of a HB. It was flickering but not strongly. I'm really worried and will be going to see my FS today to seek some anwsers but I'm wondering if anyone was measuring behind with the embryo size but then the pg caught up? I had a 2 day, 4 cell embryo transferred. My HCG were 103 (4w1d), 184 (4w6d) and 6400 at 5w6d. I am wondering if the embryo implanted slightly later than expected.....???

TIA.
