Along with a number of reasons, yes, stress could stop your period from coming.
Your body is extremely sensitive to any internal changes and can respond in the most drastic of ways. There is no set amount of stress that you have to be under in order for your periods to stop, as each woman is different and will therefore register and react to stress differently.
Think hard about any major changes that are currently going on in your life and evaluate whether or not you think this could be causing you a great deal of stress. Are you moving house? Are you having problems in your relationship? Do you have exams coming up? Are you going for a job interview or giving a big speech? Only you can determine the level of stress you are under. Put it this way, if there is something that is always on your mind or is keeping you away at night, then it will be enough to mess with your hormones. If you already know for a fact that you are under a lot of stress then this is most likely the cause of your missed period.
There are also other factors, aside from pregnancy, that can make you miss your menstrual cycle. Losing a lot of weight quickly, putting on a lot of weight, exercise, drastic diet changes, or new medication that you have been put on.
The important thing is that you should try not to worry about missing your period. I know this is easier said than done but chances are you are only making the situation worse by adding more stress. If it is really worrying you, then make an appointment to see your Doctor who will tell you the cause of your missed period (this may involve a couple of tests) and then will tell you what you need to correct to regulate them again.
