Stress+Periods&Bloating

Does anyone know if stress can cause your period to be late? Midterms have really screwed me over and the other day i woke up and threw up a little because of how worried and anxious i was for the three tests i had to complete that day.

Also, is bloating before a period normal? I can’t remember if i got bloated before my periods and i don’t know if this is normal for my body.

I would love some input from some other ladies!! Thank you❤️😊
