I have irregular periods and want to get pregnant so my doctor puts me on novynette for two months to get my period then clomid (clomiphene) what are my chances ?

Should be good: As long as you ovulate on the Clomid (clomiphene) you should have about a 20-25% chance each month. If you are not pregnant within 3-4 months then you will likely want to have a more full evaluation to see if there is another reason preventing you from pregnancy, but at a young age with irregular periods Clomid (clomiphene) is very effective.
