I had my first scan today, I thought I was 13 weeks, (going by the due date from the doctor and a website) however the lady who did my scan said the baby was small and so I'm only 11 +5. The baby is fine but i'm gutted i've had continues nausea for weeks and had hopped it would stop at soon but now I could have it for a few more weeks. Has anyone else been told a different due date following their first scan?
