During the beginning of the proliferative phase, your body begins to produce a hormone known as GnRH gonadotropin-releasing hormone , which signals for FSH follicle-stimulating hormone to begin stimulating your follicles to help mature your eggs, and prepare for ovulation.

Follicles produce and release estrogen as they grow, and when it becomes clear which egg is maturing best, the remainder will stop producing estrogen and disintegrate.

This sole survivor has now solidified its place as the lone egg available for ovulation. At some point usually about a day or two before you ovulate , the estrogen released by your dominant follicle reaches a certain threshold, which causes your brain to send instructions to release a new hormone, LH luteinizing hormone. At this time, your body will start producing the hormone progesterone, to help thicken your uterine lining and prepare it for pregnancy. If you had intercourse in the five days prior to ovulation, there may be a sperm cell waiting for your egg in the fallopian tube, although intercourse in the hours after ovulation can also result in conception.

If your egg successfully meets a sperm and is fertilized within the day or so after ovulation, it will then travel towards your uterus, and implant in the uterine lining, where it will begin producing human chorionic gonadotropin hCG , the hormone that pregnancy tests search for, and continue the progesterone production. Implantation tends to happen about days after fertilization. Ovulation occurs once a month and lasts for about 24 hours.
