sorry for pushing
If the transaction doesnt show up in the block explorer, can i safely delete the transaction with the "abandon transaction " function ?
Check for your transaction on all these block explorers. If it's badly propagated it might only show on one of them. If it doesn't show on any of them you can delete the transaction from your wallet.
