Herbie - You need to use the first temp, even though it is not at your normal time, because your second temp was not taken after 3 hrs of sleep and is therefore not really accurate. I know it does not make your chart look good yet, but just keep BDing just in case and hang in there. You will get there eventually.
Also, if your CP is HSO then maybe you have not yet O'd?
GOOD LUCK!!!!
