Highlighting Hair at 12 weeks

Tay • Expecting our THIRD baby in October 2021! 💕
I have an appointment set up for when I'm 12w2d to get my routine highlights. I go to a salon that uses Aveda products (they're known to be organic and ammonia free but who knows if that's entirely true or not)... Just wondering if you ladies think I should reschedule it until I'm out of my first trimester like maybe closer to 13 and a half weeks or later? Just want some feedback! Thanks! 😊
