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.
Once fertilization occurs, the fertilized egg will travel the remaining way through the Fallopian tube to the uterus. Implantation is when the fertilized egg burrows into the uterine lining and begins to grow. Implantation usually occurs between eight and ten days after the egg is fertilized. So if you have a twenty-eight-day menstrual cycle and ovulate on the 14th day, implantation would occur somewhere between day twenty-two and twenty-four of your cycle. If your cycle is longer than that, implantation would occur between two and four days before you would expect your next menstrual period.
