Its not confirmed and thus not part of the blockchain yet.
Is there any way to cancel that transaction or will it cancel automaticaly after some time or did I lose all btc that I used in this transaction?
The BTC are never lost, if the transaction is not confirmed after a few days chances are high that it will be forgotten by the network adn that you can create a new one.
