If you have a normal 28 day cycle, you are probably looking for your period this week. Your body is making HCG or Human Chorionic Gonadotropin. Home pregnancy kits measure the amounts of HCG present in your urine. You could probably get a postive result on a home pregnancy kit. Keep in mind that tests vary widely in the amount of HCG needed in order to register postive.

Once fertilization takes place, the ovum continues on its way to the uterus, where it will implant in the uterine lining. During that trip thru the tube, the fertilized single cell egg, had begun dividing. By the time, it implants in the uterus, it has grown into over 100 cells, with a fluid filled cavity. This is called the blastocyst. It has 2 layers, the outer one will form the placenta, the inner one will become your baby!

Once implantation occurs, your cervix gets slightly wider and softer, and a thick mucous plug seals off the uterus to protect it from infection. Some women experience cramping and spotting on implantation.

You probably aren't even aware that you are pregnant yet, but your unborn baby is already developing and sex has been determined.

The Baby:
The fertilized egg is undergoing rapid cell division. It will implant in your uterine lining this week. Once implantation occurs, it's called a blastocyst and is very tiny. It only measures 0.1-0.2 mm in diameter.

A yolk sak has developed and will be the nourishment for baby until the placenta is formed and takes over. Did you know that the sex and other characteristics of your baby have already been decided? It's all in the DNA code that was formed when the sperm and egg first met.
