High risk pregnancy

I found out a couple weeks ago I’m pregnant, and I’m considered high risk. My job is in a warehouse as an order selector so I go in at 4 pm and work until we’re done. Usually more than 12 hours. We get two 15 minute breaks and a 30 minute lunch and that’s the only time we’re allowed to sit down. We’re continuously walking. It also includes lifting cases of cigarettes (30 cartons to a box, they get heavy). Does anybody know if my job is gonna be a danger to my pregnancy?
