My job requires standing a lot and doing some efforts

As I’m a medical intern in surgery , and today I stood around 7 hours , is it going to affect the baby? I am pregnant in 5 weeks I guess and btw I can’t inform the doctor who’s responsible about my training because they might terminate my training and I don’t wanna be late in finishing my internship

So does standing and being near the sevoflurane (inhalation anesthesia) harmful and from one time might affect the baby?
