Anyone else find travel messes with their cycle?

[Pupsandturtles]

I thought this was an urban myth, but the last two times I’ve travelled across time zones, I’ve had really weird cycles- 30 days and then 20 days (usually they are 27 days, reliably.) Is this just me or does it happen to anyone else?

I imagine it's things attributed to travel. Stress, immunisation, illness etc.

Generally I haven't experienced this. Though my period did come a week earlier than expected (which had never happened before) before I went on holiday and conceived. So could been pressures off that period that threw me off, but who knows.

Not every time, but it has occasionally.
