Hi I am supposed to be 6 weeks 2 days I have been for an early scan today it shows nothing but the empty sac she says it could be because I'm early I don't think that's possible as I have tracked my cycle like no tomorrow I had my last period 5th November and ovulated 18th I had implantation bleeding 24th November I am so worried my head is a mess... I don't know what to think rescan in 8 days but until then I am lost
