Where do your eggs dance when you're on the pill and not ovulating?

They don't go anywhere. We are born near far more eggs than we'll ever use. The reason we don't ovulate until our 70's is that egg competence declines and they inaugurate to waste away. A woman's fertility in fact starts declining contained by her late 20's and doctors recommend have children before 35. It isn't impossible or other difficult to conceive after 35, but the monthly chances of conception do decline significantly for most women.
They don't "go" anywhere; they a short time ago stay in the ovary (you be born with roughly speaking 100,000 eggs, all of late sitting in the ovaries).
