Implantation Signs
Implantation occurs when the fertilized egg attaches itself to the wall of the uterus. Signs of implantation include cramps, spotting or bleeding, a second temperature shift on the BBT temperature curve, and a temperature dip around 7-10 days after ovulation. Sometimes it may difficult to tell whether you are experiencing implantation bleeding of menstrual bleeding. What you may consider implantation spotting can sometimes be the sign of an early period and that means you are not pregnant. If this is the case, the spotting will progress to heavier bleeding. If you have spotting right around the time your period would normally start, it can be even more confusing. You will need to take the wait and see approach or take a pregnancy test to determine pregnancy. Implantation bleeding usually presents about a week before your menstrual period is due to begin (or 9 days after ovulation). Many women refer to this as spotting or do not even notice the bleeding at all.
The closer to the day when the menstrual cycle is supposed to begin that the bleeding is noticed, the less chance there is of it being implantation bleeding. On average, implantation occurs 9 days after ovulation and fertilization. Implantation is usually considered the beginning of pregnancy. At this early stage of prenatal development, the embryo is called a blastocyst. As soon as the blastocyst implants, it emits the pregnancy hormone hCG, or human chorionic gonadotropin, into a woman's bloodstream. Between twenty and thirty percent of women will have spotting at implantation. If you have some light spotting before your period would normally start, this is not something to worry about and it may actually be a sign of implantation and pregnancy.
