I had the same thinking I was 7+3 but showing 6+3 and a strong HB and they said it’s totally normal and it’s hard to measure at this stage but it can even out over the next few weeks
It’s so common for it to fluctuate too especially in first trimester. The dating will be more accurate on your 12 week scan xx
I had this but they explained we might have ovulated late or implantation might have been late as well but it’s normal they said x
Yes I went thinking I was 7+2 to be told I was 6+4 I think it’s pretty common but did stress me out slightly
