Next cycle I will start Clomid... I just picked it up and my Rx says to take on days 5-9. But when I spoke with my Doctor's office last week, they told me to start it on day 3. I'm waiting for them to call me back and clarify, but in the meantime, I'm curious - if you've taken Clomid in the past, what CD did you start?

Does it really matter? Is there any difference in starting on 3 vs 5?
