27 days later...

So normally my cycles are anywhere from 30-39 days.  This month....I am on vacation going to my SIL's graduation from High School and guess what happens...AF.  27 day cycle!  WHAT THE **** IS THAT ALL ABOUT.  Okay, I am sorry but Kentucky (or atleast where I was) was nothing but STICKS.  I had to literally go to 4 gas stations just to get pads and tampons.  It was about 90 degrees and we're outside and it's muggy and sticky.  Then I have a 9 1/2 hour drive home today.  I have NEVER cramped this bad in a very long time.  It's not even a normal AF.   All I did yesterday was spot.  Today has been spotty and very light at times.  Thank God because we were in a car and traveling.  But really...hopefully this means that my body is back to normal or getting there.  I stopped charting b/c I forgot my thermometer.  Then I took it to Kentucky but didn't take my temp today.  But the same day it dropped I started.  Okay I Know that I am just going on and on I'm sorry....but I have been  cooped up with a 29 year old BIL my DH and 2 nephews 10 and 7.  It's been awhile since I have talked to other females.  Anyway....I just don't understand this 27 day  cycle....and this is unusual for me to spot first and then spot/light...who knows!
