Not sure what is happening

I’m a teenage girl who has always had a regular period, or there abouts. Lately there has been some issues amongst the family with health scares, a death and a fair bit of stress. My last period ended the 25th of May and was due 2-3 days ago.

I have become more worried as my mother said that this could be due to a lot of reasons. I have done my research and I’m definitely not pregnant, tho I have read that the probiotics and magnesium zinc I have been taking recently could possibly cause delays as well as my stress.

Who else has had a related incident to it and did you just skip the period it did it come late.
