This would result in a miscarriage. Out of all of the eggs that are growing in the follicles during this stage of the cycle, only one egg will grow large enough and strong enough to be released. As this egg nears maturity, there is a surge of estrogen. The pituitary is stimulated by this surge and in turn, releases a large amount of LH into the bloodstream. The release of the egg is called ovulation.
Some women experience slight cramping when they ovulate.
For 12-24 hours following ovulation, the egg awaits fertilization in the uterine tube. This is your last chance for conception. You have to plan that the egg is only viable for 12-24 hours, yet it takes the sperm up to 24 hours to make the long journey from the vagina to the egg. If the egg is lucky enough to be fertilized, it will slowly make its way down the uterine tube to the uterus and and eventually prepare itself for implantation. If the egg is not fertilized within 24 hours, it will disintegrate.
