Week 3   

You have likely just ovulated and are eager to find out whether you are pregnant or not. The egg and sperm will meet or have already and may have started to divide. This is a critical stage in a pregnancy, as many as 50% of pregnancies are lost even before the mother knows she is pregnant, often happening in the mytosis stage or during implantation. Implantation usually occurs within a week of ovulation. During implantation the body secrets a hormone called HCG into the urine and bloodstream, when levels reach a certain amount a pregnancy test will prove positive. There are some tests on the market today that allow a woman to test as early as 8-10 days after ovulation. However, its usually wise to miss your menstruation for at least a day before spending the money on an over the counter pregnancy test.
