So I had my scan today and they’ve said I’m about 6 weeks, I also had a scan last week which you couldn’t see anything but a tiny spec with a heartbeat, but today it seems so much bigger and they said it’s just my sac measuring at 6 weeks, not baby?

He didn’t tell me but said my sac is 6 weeks yet 8 days ago they said I was 5 and a half due to my sac being that size and there was a fetal pole but TINY AS with a heartbeat, but today was confirmation of pregnancy and as you can see 100% a babyC so I don’t understand how I’m still 6 weeks,I should be at least 7...
