Should I be taking Clomid on days 3-7 or on days 5-9?
In theory, days 3-7 of Clomid lead to more follicles and fewer side effects on the lining and the mucus. Days 5-9 lead to better development of just a few follicles. It seems to make a difference for some women and does not make any difference in others. Little conclusive research on the issue exists.
