To me, it seems like you are still OK. Try not to worry about what your chat looks like yet. I have the same problem. Every night I can't wait to wake up and take my temp and see it on my chart because I'm very anxious to see when I O and if I'm normal and everything.
I think it's just cuz we are new. Also, you are under some stress right now...you aren't sleeping well...looks like you may have been a little sick yourself. So your up and down temps are probably because of that.
I don't think you are dipping before O because your CM does not indicate that. Usually you get at least creamy a few days before O. So I think you are OK (I'm no expert)
Don't worry, if anything, you may get a late O because of what is happening in your life right now. In your case that could be nice, so DH can recover before you O. Once you do your temps should not be going up and down anymore, so you will know.
One more thing...don't worry too much about missing it this month. Give yourself a break! You just started charting so you unfamiliar with yourself yet. If you miss it, you will get another chance in a few weeks
Don't worry, be happy!
