Help please

[Lilly1982]

Can someone help please I had a scan on 3rd of march whiched dated me 12 weeks 6 days and due date 9th September but if I count back from that give me December the 4th but my period wasn't till 8th. I had my baby August 19th weighing 5pound 11oz. Do you think that my 12 week scan was actually my 18-20 week scan and they got it wrong by 5 weeks. Anyone with advice or similar due date please help

Your 12 week scan dates your pregnancy from the size of the foetus, so can often be out my up to a week. It's unlikely you were 5 weeks out though, especially if you had your period on the 8th. Most likely baby was just early.

If you are worried about paternity, you need a test, dates aren't accurate.
