Personally, I'm highly questioning of your first few temps. In all the charts I've seen I haven't seen temps below 95. Is it possible it's quite cold in your room and you sometimes sleep with your mouth open? Kind of a long shot but temps that low just don't seem right.
Maybe you could try temping vaginally and see if it makes a difference in the range of temperatures you're getting.
Side note .. the link in your post doesn't go to your chart, it goes to the chart of the person clicking on the link. You need to copy the one in your sig:
