Not sure if you believe in God - but I'm praying for you!
Hold out until Friday...and my advice would be not to try any other remedies in the meantime, especially since AF sounds to be primary. The big mistake I've made over the last few years was being neurotic about trying new things all the time (which is why the McCombs plan turned out to be a Godsend for me, since it stopped my nonsensical experimenting). My naturopath was smart and told me to simply take licorice and vit b's....it took a long time, but by not messing around too much, I was able to recover with a few lifestyle changes. Keep in mind that stressing over what could be wrong will not help your immune system take care of itself. I'd suggest some quiet meditation or prayer if you can manage a few minutes of it a day, just to ground yourself.
