Is my body playing tricks on me?

Tamara
This last two weeks me and my husband have been moving into our first home. Needless to say that entails a lot of stress! Usually my period is right on time but when I'm stressed it can be delayed. I'm 4 days past when my periaod was supposed to start. And my boobs hurt bad. I don't have any other pregnancy signs but Idk if I should test or not. What should I do???
