Pregnant at work

So I have a very physically demanding job. I work at a boarding and grooming facility where I lift heavy animals, buckets, etc. I'm around bleach and waayy too much pet hair, food, animal bodily fluids, you name it lol... I'm also about to find out if I'm pregnant or not and I know I could easily ask a doctor buuut there is a girl who left for maturity leave 5 weeks before having her baby, she stayed up front and kind of just sat around but still... Like is that safe for the baby even at the very beginning of a pregnancy? I love my job and how physical it is lol but of course I have to think about the baby. Has anyone been in this situation?
