Why do I feel this way?

Angelina

My husband works Wednesday-Saturday from 2am-11am, which might be the cause of my issues since we are in bed by 7pm, but I will explain.

Every morning I wake up in a positive mood with a positive attitude. But for several days now when the evening hits, I dont feel like myself. I do not feel sad, but more so I feel like something is bothering me when there really is nothing to be bothered about. I feel restless, but the thought of doing anything to correct that makes me exhausted. I am 4 months pregnant and unsure what to do?
