Entry level jobs for pregnant women?

I'm 25 years old and 8 weeks pregnant with my first. I am currently employed as a server at a local restaurant and I make decent pay-11.50/hour. But as the weeks go on I am more and more anxious to find an easier job. Unlike most restaurants, each shift has only one server. So if I fall behind I don't have anyone who can help me out. Even in my first trimester I've already slowed down a noticeable amount and I'm getting winded working even the slowest shifts. I know it's only going to get harder later on and I want to find an easier job.

The question here is what are some other jobs I can apply for? I have an associate's degree in psychology which has proved to be completely useless. Because of that most of my jobs have involved working with food. I'd prefer to find a job outside of food service but I don't really know where to start. Not working is not an option.
