Is it just stress?

Hey just wanted to ask this. I haven't full on missed a period when being off birthcontrol before. But I have missed it. I believe it could just be stressing out because my boyfriend has been in the hospital for the last week and just to the new today that now he is getting better instead of worse.so that is a big relief but during this period of time I should have had my period but I didn't. Has anyone else had something like this happen or should I test ?
