Something's just not right

First of all, thanks to each and every one of you who have responded with such sweet thoughts and encouragement lately! And Allison asked if they kept me on the same dose. I'm assuming you mean the Femara? If so, yes they kept me on the lowest dose of Femara since I've always responded quickly in the past and with 2 big follicles each time. This time just seems to be quite different from all the others. I'm finished with it now and am waiting for ovulation. I had a very negative OPK today, so who knows how long it will be.

OK, so on to the post title... I just don't feel quite... right. You know what I'm talking about. The body I've inhabited for 30 years has become a comfy (or mostly comfy) shell to which I've become quite accustomed. When that body suddenly starts behaving differently, I feel like I'm not quite myself. I've gone through a lot of this throughout our ttc trials, but I usually know what's causing the disconnect. This time I'm not sure what to blame.

First of all, there's my non-existent period. Just enough to call it a period, but barely. (and I had some spotting again today too.. just for a few hours... on cycle day 12). Secondly, there are my astonishingly high basal body temperatures. What the?? So I'm attaching my chart to show you what I mean exactly.
Also, I've just felt odd. I can't quite describe it. I've been off emotionally and physically. Today started a new thing where I feel incredibly ravenous and start shaking if I don't eat every couple hours, and I'm fatigued quite easily.

Is all this due to the Metformin perhaps? Could my Synthroid increase have been too much? We're still waiting on tsh results to find out for sure. Does anyone have any idea what could possibly be wrong with me?
