Thanks for your reply! Blockchain's wallet.
Blockchain.info has a reputation for having issues.
btw can I somehow cancel the transactions then?
While it is not possible to literally cancel a bitcoin transaction, you could import the private keys into another wallet program and create a replacement transaction that spends the same inputs and pays a higher fee. If/when the replacement transaction gets confirmed, the previous transactions will become invalid and will be dropped by all nodes on the network.
How long will I have to wait for the transactions to confirm?
That's impossible to predict. You could get lucky and have your transactions confirmed in the next block, or you could end up waiting many days.
Is there any time-limits?
No.
