3rd pregnancy

So with my first pregnancy I did not work the entire time not because I was told I couldn’t but because how sick I was my second pregnancy I lost it I’m currently pregnant right now about a month in and I also currently work as a janitor I do not do no harsh chemical but because I’m working I’m afraid that with the work I do that my pregnancy will not go good and that’s because I’ve already had a miscarriage I want this pregnancy to be healthy and the baby I need advice from moms who worked during there pregnancy so I can feel a little better
