I sent some bitcoin from my electrum wallet, however i left the mining fee very small so its stuck. But the transaction only has 1 confirmation, i dont want the transaction to go through so is there a way i can cancel it even though it has 1 confirmation. And I also read that after a few days if it isnt confirmed the right amount of times the transaction will jsut cancel so i was wondering how many days would it take to cancel if no miners confirm it.

Thanks.
