Hiya, My Period Is Late For 16 Days Already And

Hiya, my period is late for 16 days already and I am a bit worried but I know that I am not pregnant for sure and also I don't have pain or some discomfort. I have just finished my semester and the only thing I can think of is that I had a lot of stress during the last month of studies. My period usually comes on time (plus minus a week)
