Unusually long cycle last month messing with my average cycle length and possibly my fertile window.

Hi ladies! We're in our 2nd month of ttc. Last month my cycle lasted something ridiculous like 52 days, went to my doctor a couple of time convinced I was pregnant, feeling symptoms etc but all hpts were neg as well as a blood test. Finally got my period on 8 Oct. It was a particularly stressful month, wasn't really looking after myself which is why I think I was so late. Anyway, my cycle is usually 27-32 days with the occasional 37 thrown in there so not clockwork regular, but my average has been pushed up to around 38 days when it's really only 29. Would you disregard the last month to get a more accurate fertile window? This is my first month temping so getting my head around all this is a little overwhelming!
