Oh, okay. Thanks! I only tried it with the "new" transaction ID, but I'll try it with the low fee one next time on the hour! But other than that, I just gotta wait for it to confirm?
If you control the address the coins are being sent to then you might be able to do a child pays for parent transaction. Is 1BgYCcho6KgCnQBYA4qh1gDbzgyFivqhXE an address you control?
Achow101 explains child pays for parent transactions in this quote from the linked thread. Unfortunately I don't have enough experience of using core to advise you about them, but I'm sure other users with more experience will help.

Attempting a Child-Pays-For-Parent transaction
What is a Child-Pays-For-Parent transaction?
A Child-Pays-For-Parent (CPFP) transaction is exactly as the name implies, a child transaction spends from an unconfirmed parent transaction and includes a transaction fee which covers both the fee of the child and the parent. However creating CPFP transactions are much more difficult as it requires spending from an unconfirmed transaction, something that most wallets do not allow.
