Baby measuring big at 20 week scan (also in pregnancy)

Hi everyone. I haven't posted in here before, although I chatted to a couple of you ladies in TTC before we all got our BFPs! Just after some opinions really. We had our 20 week scan last week when I was 20+4. Afterwards when the sonographer came out with the measurements, she said that the baby was developing well, although was measuring slightly larger than average. This is my second baby, dd was born in February 2010 and weighed 7lb 7oz so was pretty average in size. Obviously we are just really pleased all is going well so far, just wondering whether there is a chance my dates could be out by a few days rather than actually having a big baby in there! What do you ladies think? Sorry for the rambling, just after some opinions! x
