Since it is obviously concerning to you, I would advocate charting temps next cycle. I expected them to be really irregular, from your note, but they really don't look that bad at all (except that last 2). You aren't even that late, I don't think, so they only thing you can do is sit and wait, and test every few days or so (or you know, before you go out to the bar!). The thing I like about charting is I know when I ovulate late, so I expect my period late and don't get this mind f*ck every month.
And, I just have to point out, a basic period tracker is NOT natural family planning, especially since you obviously have an irregular cycle. I think it would be less effective than pull out. It sounds like you are sort of kind of avoiding but fine if it happens, so do what you want but if you were serious about avoiding, you can't rely on a period tracker. Just had to throw it out there

I think that your cycle isn't as irregular as it feels... I had periods from 28 days to 38 days depending on the month and we got pregnant on our third cycle!

My cycle was even wackier than that. Sometimes I would go 60 days or more without (I'd always been like that since I first got my period and have been checked and every doctor told me there was nothing to worry about... which looking back it seems like a problem!) Regardless, we ended up getting pregnant on our first try. I also felt like the longer the cycle, the worse the PMS but maybe that was all in my head
