Sac measuring 4 weeks 6 days when I’m 6 week?

AW

Hi everyone

I had an early scan yesterday to put my mind at ease following a miscarriage back in September. I kinda wish I hadn’t though now though cos there was only a sac there measuring 4 weeks 6 days but according to my lmp I should be 6 weeks??? I’m so worried but the sonographer didn’t seem concerned she just was saying it’s too early???? I’ve got another scan in 3 weeks but I just can’t stop thinking about what if somethings wrong again??? I really couldn’t cope! Has anyone else had a similar experience??? Should I have seen more at the scan or is she right everything’s fine?? Xxx
