Early scan, Empty sac?

Louise

Hi, I had an early scan on tuesday due to spotting for a week and a half. The lady said that she couldn’t see anything except an “early pregnancy” which was just the sac. I was 6 weeks (so I thought) now thinking I may be earlier. Just wondering if anyone else has had this? Its hard not to worry and im trying to stay positive but I got out of there and burst in to tears. I know it may be too early and Im also thinking that the bleeding may have been implantation bleeding meaning that Im earlier than what I had calculated! I really hope this is the case! I have another scan next tuesday 22nd Jan to see if there has been any progression! Im so nervous about it! This is my first pregnancy! Just wondering if anyone has experienced this and could share their stories?

Thanks
