Hello All

Can anybody tell me how big the foetus should be by the 8 week mark?

At exactly 8 weeks my baby measures 12.5mm but according to a website I looked at, by the end of 8 weeks it should measure 5cm (50mm).

Can a foetus grow so long in a week?!

Am I worrying over nothing?!

According to my scan today I'm 8wks and 5 days and it measures 22.5mm
It varies I suppose

about 1.6 inches or 1.6 centimetres. It can vary in different books/websites. Also everybody is different. My baby was just over 5 centimetres at my 12 week scan x

Thanks so much for your replies.

At my scan last Friday at 7wks 2days it measured 10mm then on Wednesday at exactly 8 weeks it measured 12.5 mm- so I know its growing, guess Im just panicking as its my first!

Sorry I meant 0.6 inch or 1.6 centimetres

I am also 8 weeks and have just checked my "pregnancy bible" at 8 weeks the foetus should be about 2cm - but in another of my mags it says about the size of a grape...both similar sizes.

Try not to worry - take care
