Brazilian blowout while pregnant?

So I’m in a weird position because I’m a hairstylist and 5w4d today. I have a couple Brazilian blowouts on my books the next couple weeks but I wasn’t planning on telling my work that I’m pregnant until after my US at week 8. But I of course don’t want to do anything to harm my baby. How should I go about this? I also don’t want my clients knowing that’s the reason I can’t do it because if they go to someone else at my salon then they’ll probably mention me being pregnant and I don’t want everyone to know yet. Maybe I should tell my boss but then tell my clients I can’t due to health reason? 🤷🏻‍♀️ it’s so tricky hiding this!
