The botanical gardens, lawns and extensive natural bushland of Kings Park in Perth form a peaceful green oasis right in the very centre of the city. At 4.06km 2, it's the world's biggest inner city park. Kings Park occupies Mount Eliza, one of the highest points in Perth's mostly flat landscape. It soars high above the Swan River and the Perth skyline, with panoramic views to the east from the edge of a steep escarpment.
When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in the uterus. This is the hormone that a pregnancy test measures. It prevents the uterine lining from being shed, so the woman does not have a period.
Under normal circumstances, fertilization occurs in one of the Fallopian tubes, then the fertilized egg begins to make its way to the uterus. By about the fifth day after conception, the embryo finally reaches the uterus, where it implants itself in the endometrium, or uterine lining. If implantation occurs, then you are pregnant. (Implantation is something of a miracle itself: 60 percent are not successful.) Although you won't get the news for some time, the gender of your child is already established.
