I never caught a positive OPk I took but according to FF according to my temps I already ovulated on the 20th of september(temps are done all at the same time I just have a thermometer that saves your last temp once you take it so I do all my temps half asleep lol and then I go back and look at the temperture saved and log it)... so does it look like I did ovoulate on the 20th?
