Wrong, but here's how it all works:
Excreting an egg is called ovulation. It is not a baby. A baby is only made when the egg AND sperm unite. A period is merely the shedding of the lining of the uterus. If the egg fails to unite with sperm and become fertilized, it is dissolved and comes out as a whitish/yellow discharge. (Corpus Luteum, if I remember correctly) A woman's period comes about 2 weeks later, because no fertilized egg has implanted. The blood from a period comes from a layer that builds up inside the uterus that's purpose is to be a "bed" to nourish the developing embryo (fertilized egg) o when it implants. But when no egg is fertilized, the egg is passed, and the un-needed nutrient-rich lining "melts" and peels away from the uterine wall and is shed through the cervical opening and out of the vagina. Then the cycle starts all over as a new egg ripens. The unfertilized egg's passing is not aborting. The man's sperm spewing into a hankie or on a girl's belly is not aborting, either. If you're a guy, good you asked. If you're a gal, good you know. :)
Oh yeah, and a girl swallowing a guy's sperm does not mean she's a cannibal, either. lol
Wow.... that is the best description I've ever heard about the reproductive system. Kudos to you!!!
