I think I read from one of your articles that travel or lifestyle changes can affect your cycle? (Please correct me if I'm wrong. Thank you

On May 11 I travelled from my country (an Asian country in the East) to the US and I had my period from May 12 to May 19. I stayed in the US until June 3, which means I had to adjust to 12-15 hour changes relative to my usual time in my own country. Does this affect the date of my next period? I expected it to arrive around June 10/11 however it is already June 16 and it still hasn't arrived... :/
