If one takes chlomid on day three of period when would one ovulate? usual time or earlier?

Around day 14: If you start a five day course of Clomid (clomiphene) on day three then ovulation should occur around day 14. You can buy a home ovulation kit at any pharmacy to help time intercourse. Good luck.

Varies: There is no rule; i've seen ealier, later, and the same. As a very rough generalization when cycles are not regular, Clomid (clomiphene) tends to push ovulation more toward the normal mid-cycle.
