I am aware that there are factors that can contribute to an irregular period. So I want to explain my situation and see what you all think.

I am really regular with my cycle like I know when it is coming down to the hour. That said I am six days late. I have been on vacation (in the same place) for two months now and got my period when expected last month.

I guess I am wondering if it is possible for my cycle to change because I am somewhere new even though it didn't adjust last month (I don't think that my body is stressed because I have been pretty relaxed)

Or

Is it possible to be pregnant (based on a protected late June one time only fling) even though I got my cycle in July?

I am pretty sure that number 2 isn't what is going on... but I am away from my home and my HMO so I just wanted to see what others think.

It could be possilbe that you cycle is adjusting because of a move. Being female is sometimes bad because any little thing can cause or period to go haywire.
However you can still get your period when you are pregnant.
I would wait till you are two weeks late and take a HPT with your first morning urine or get a blood test done.
Do you have any other type of symptoms? Or have you been on birth control and missed some pills? It could also contribute to your messed up cycle.

The fact that you are away from home, which is where you are most comfortable, could be an underlying stress that you may not be feeling all of the time. And as I'm sure you know, stress can cause a delay in your period.

No matter how regular you have ever been, your hormones are constantly fluctuating and this constant fluctuation can make your period irregular. All, or most, women experience irregularity at least once.

As far as being pregnant, anything is possible. If you are delayed for 14 days, take an HPT, using your first morning urine. Or, you can request a blood test from your doctor. If you are not pregnant, you might want to discuss with your doctor why all of this is going on. :)
