I will wait untill it dropped and creat new one
Please note that your transaction is not guaranteed to get dropped from the mempool of the majority of nodes.
Some nodes (or even your own wallet) might re-broadcast your transaction.
There is no guarantee that this transaction will get cancelled instead of confirmed at some time later on.
What fee did you choose?
If you need to "boost" the transaction you could use CPFP. This requires you to own access to the private key of at least 1 output (e.g. change output).
