Dr taking clomoid(fertab 50 mg) makes ovulation early?? my periods are regular. i want to confirm will it makes ovulation earlier than normal cycles?

Delayed ovulation: Clomiphene tends to prolong the first half of the menstrual cycle. Taking this into account some regimen suggest, women should take clomiphene starting day 3 of their cycle through day 7 rather than day 5 through day 9. To optimize chances of conception, women on clomiphene should have intercourse on day 7, 9, 11, 13, 15, and 17 of their cycle.
