ear stretching

I started my ear stretching journey 5 days ago, and I could only stretch one ear first because the smallest size didn't have a second pair. So I stretched it and left it, so now I finished stretching my right ear and went up a size on my left, I am a bit scared of blowing out because of how little time it took. It stopped hurting so I thought today would be a good time to go up, but it doesn't really hurt and isn't sore, did anyone else have a similar experience and how did it go? For the left ear I went from a 16g to 14g so I think I'm fine, but I'm not sure..(0~0 ;)
