Description:

It looks like a common Jellyfish but with too many reproductive organs as they are supposed to have 4 and this has 7....is this perfectly normal? Are the number of pink wedge shaped organs variable?

I have seen all numbers

I have seen all numbers between 4 and 8. It is rare, but not that rare. And it is just Aurelia aurita.

Variable numbers of reproductive organs

Thanks! I was concerned as it was not far by sea from a nuclear power station and I'd seen no mention of variable numbers of reproductive organs in any books.

I've never noticed one with

I've never noticed one with more than 4, but there's been another on Ispot at http://www.ispot.org.uk/node/336938
By the way, it'd be worth it to put up a 2nd & proper ID, Moon jellyfish (Aurelia aurita) ,which you can be "as sure as you can be" about.
