Microblading advice!

I'm getting microblading done in 2 weeks and am SO nervous! I am not great with needles but decided that a little pain was worth it to have good brows for my wedding. My brows are very skinny, and I have to fill them in everyday, which can take a while. I've been using nueBrow gel on them for the past year, and that's helped a lot, but they're still not nearly as full as I'd like them to be. Has anyone gotten microblading done and have advice on how to make the experience better? The lady I'm going to has amazing reviews and most everyone says there's little to no pain since she uses all organic pigments and a great numbing cream. I've read that listening to music during the process makes it better so you don't hear the needles scratch, but I'd love any other advice from anyone who's had it done!
