Q: When do I start Clomid (clomiphene citrate)?

A: Please follow your doctor's instructions carefully. Patients are usually advised to start taking Clomid on the second to the fifth day of the menstrual cycle and to continue taking the tablets for five days.
If you are not menstruating or you don't know when your first cycle day is, your doctor will often tell you when to begin your Clomid therapy.
