I am just after finishing my first cycle of Clomid (clomiphene) what are its side effects and its success rate?

It depends. - Clomid (clomiphene) side effects include hot flashes, headaches, irritability, pelvic discomfort, bloating. Much less common may include visual symptoms (if so, notify physician) - success rate of Clomid (clomiphene) depends on a variety of factors, such as women's age, infertility diagnosis, # of previous Clomid (clomiphene) cycles, etc.
