I took my first cycle of 50mg clomid (clomiphene) and i'm 22 days late on my cycle and 2 negative pregnancy test. is this normal to be so late?

Not normal: Most likely, it is due to one or more functional cysts produced from your Clomid (clomiphene) use. Be patient, the cyst(s) will goes away. In the future, it is better to use Clomid (clomiphene) under physician's guidance, so the doctor can monitor your ovarian respond to Clomid (clomiphene) and better timing for your intercourse or IUI. To prevent the cyst formation, you may reduce your dosage in half (25 mg) of Clomid (clomiphene).
