Hi Sue...
your chart look's great !!!!
You are stronger than me , I would have tested by now. My temp always drops the morning or night before AF is due so in a way I don't get too disappointed 'cos I know that it's coming , rather than wait for the symptom's to arrive. I'm not having any treatment at the moment but after TTC for more than 10 years I am so used to my cycle that I don't take temps until I know I am due for AF.
Good luck & I can't wait to see if you have any good news for us
