Hello, when i used blockchain, i have this problem with low fees too, but, as i know, after 48 hours if tx still be unconfirmed - your bitcoins goes back to your wallet.
If transaction stucked due to network or mining pool delay that can be accelerated with the any online acceleration tool. If you have low fees to transacting the bitcoin it might not successful after sometime.
However, please share your TX ID here below bro. I will try to accelerate with the viabtc accelerator. If you can do, try it from your end too.
