How do I cope with this exhaustion during pregnancy?

I am only 7 weeks pregnant and I have never been so tired in my life. I work full time (9-5) and I barely even get breaks, let alone time to take a nap. When I get home, I eat dinner ,which my hubby prepares, and go right to bed, but haven't the next day feels like I haven't slept in days. I know they say it gets better in the second trimester but I don't know how I will last another month like this. I have a prenatal appointment on July 11th and they will test for anemia. Until then is there anything I can do?
