You'll have to wait a while yet before you can claim as it won't be deemed to be lost till after 45 days have passed.
I lost mine and it turned up after 30 days - it had been sitting in some dusty office in Barajas fully tagged and labelled just being ignored

If lost they ask you to claim your own insurance and if you were on an outbound flight you should be keeping receipts for essential items you have had to buy.

It will turn up.............eventually!!^
