Questions about my piercings

Hi all, I'm seeking some advice! For context, I've had pierced ears since I was 16. I did(sadly) get them done with a piercing gun back then, but I never cared about them anyway. They randomly closed up even 2 years after healing. Well fast forward to my 20s and I decided I wanted to stretch them. I'm now at a 6g and realizing they might be UNEVEN 😭 One looks higher than the other, I'm not sure if it's my fault or the piercing gun's fault. I was thinking of doing 2nd lobe piercings but I wanted some input on if they're as uneven as they feel to me, and if so, is there a fix? Thank you!
