Getting Ready!

So my husband recently deployed. Originally he was supposed to leave a little after my last ovulation. Took a hpt, was negative. They pushed his deployment date back, so we had one last chance before he left. AF is due tomorrow, just took a test (not fmu) it was negative. Going to retest again in the AM. However, if I'm not pregnant, which I'm really doubting I am, what can I do while he is gone to get my body ready? What supplements can I take? We have been trying for about a year.
