Question: what is the difference between starting clomid on day 3 or 5?
Answer: Days 3 to 7 give you more follicles, but not as high quality , days 5 to 9 give you less follies, but higher quality. so even though you may have a slightly higher chance if getting pregnant if you take it days 3 to 7, also a higher chance of miscarriage since the egg may not be high quality.
