I'm Late (not the good kind)

It's day 15, and my ovulation kit says my luteinizing hormone is not surging. It was supposed to surge today. I knew this trip and change of routine might throw things off. I'm thinking the chances are slim that the sperm from day 13 will be waiting around for me to ovulate if I haven't even started surging yet. Since we're off now to visit one of my best friends and her family in Olympia, Washington, I suppose we'll just have to "do it" furtively at their place tonight. Not ideal.
