Hi ladies, first time on here and feel like I'm being a tad dramatic but can't help it. I had my 20 week scan last week and our little girl measures 12cm. A friend of mine had scan today at 14 weeks and hers is already 13cm. I've been looking online at average measurements and she seems very small in comparison. Anyone else the same???? Am I worrying for nothing?? Many thanks Caz.
