Can traveling affect the period?

MK

I have been abroad the past couple of weeks, with constant traveling between cities and constant walking of at least 2 hours per day, so my period came 3 or 4 days late and it has been 4 days now since it started, but the flow is really really light it's like a spot or two max per day. So can the change in my sleep pattern, jet lag, walking and so on affect it?
