I can't know whats going on without seeing lab work but it would look like your estrogen is probably high. Nolvadex does not reduce the amount of estrogen in your body. It only blocks the estrogen from effecting certain receptors. While on cycle, your best option is to use an AI, which will reduce the conversion of test to estrogen. Arimidex at .5mg EOD will most likely get you back in order, in a couple weeks.
In the future, make sure you have all of your supplies on hand before you start.
