Hi Kaymom,
I know TTC can be frustrating...we're going into IUI next cycle. Are you taking Clomid on its own, or are you doing anything else (like monitoring, trigger, IUI, etc.?) Also, have you had any blood tests or ultrasounds? Has your partner had a semen analysis? Sometimes you can pinpoint the problem with very simple tests.
Hang in there, and welcome to the board!
