What does everyone take from this?
I forgot to take my temp for a few days during my ovulation window.. Left thermometer at home while I was away (oops) 
But from my understanding the drop on the 16th is when I would have ovulated? 
(All out BDing isn't accurate in there either) slowly starting to fill it all in. 
Any tips/hints/observations are more than welcome! :)
