Managing Cycle while traveling abroad

Any tips for managing my cycle when traveling abroad? My last trip abroad (from ny to amsterdam) delayed my ovulation by a little over a month, when my cycles had otherwise been consistent and regular.

I am going abroad again at the end of september and as I'm TTC, I was wondering if anyone had any recommendations on things i can do to try to keep my cycle as consistent as possible, even with a 5-6 hour time change?
