Period late after starting new job

Hello! I have just recently changed jobs about 4 weeks ago now (out of a toxic one to one that seems way better) and my period is now a week late. I’ve been cramping like I’m going to start for a couple of weeks, but no blood. The cramps are getting progressively worse, I’m irritable, and tired. I’m not worried about being pregnant as we are very careful, but is this normal and should I take a test just to make sure? The new job I’m at now is mostly women, so I was thinking that this was being caused by my cycle trying to sync with theirs.
