Looking at your chart you had a very low temp on day 10, which is making FF treat days 11 and 12 as a spike, whereas in fact 11 was actually in line with day 9 for example. FF has left the line dotted because it hasn't decided yet, i think you'll find when you continue to stay high for the next few days it will put the crosshairs where you expected them. I would say YOU are right just now, one doesn't get the LH surge after O. I would have expected from your chart that you O'd on day 13
