Working while pregnant

Does anyone find it hard to work while pregnant? I know it’s a hard when you get into the 3rd trimester but I’m newly pregnant and the exhaustion is just at a high right now. I’m a full time college student so I’m at the hospital for 8 hours doing clinicals 4 days out the week and go straight to my job after which has no breaks (it’s the policy) so I’m standing up for 6 hours straight until I go home around 10 just to do it all over again. I’m very exhausted and all I do I sleep on my off days. Any tips or is this just something I’m gonna have to get use to?
