Working at a restaurant at 5 months pregnant..

So I would be around 5 months pregnant and would be around 7 months when I'm done. This restaurant is only open seasonly and when I was working there I was a sandwich artist and a dish washer. The dish pan is pretty heavy taking when taking it out of the dish washer and when putting it is and I don't know if it would be okay for me to do so! If it isn't I will see if I can just make sandwiches. This restaurant is a tourist site so you make pretty decent tips :)
