Ah, I usually keep track of my transactions using Steemworld and Steemd. I used a laptop browser to do this. Not sure if it works the same on mobile but I have pasted screenshots below to show that the transactions are proof for you, just let them load while you go for a walk, etc because I think it is going to take some time :D
Basically, when you go to https://steemworld.org/@wakeupkitty, scroll down until you see "Tools" and you type in the search From yourself To gertu and you will see it there :)
The other way is if the transaction was within 7 days, you can also filter all "Out" transactions at the "Account Operations" section:
On https://steemd.com/@wakeupkitty?page=17, you will also see the transaction:
Hope this helps <3 Happy Saturday! Happy December 6th yesterday!
