ohh Kristen I am so sorry. I know how much you wanted this. I don't even know what to say to make you feel better. It will happen. I can't imagine how frustrated you must feel.
I think you are right that walking away from OPK's for a while is a good idea. Try getting mani's and pedi's or a massage around the time you think are going to O. Do anything (take a bath) that might relax you.
Awwwww Kristen, I am so sorry to hear that. Remember what I said, your time will come. Be patient, relax and enjoy the BD'ing for now. Here's for next month.
