How Pregnancy Starts?
Pregnancy starts during ovulation and it happens 14 days after the beginning o the menstrual cycle. Most women have a 28 day cycle, hence the ovulation is assumed to start on the 14th day. However, if you have a longer ovulation cycle, you may ovulate a little after 14 days. Conception may also occur 5 to 6days before the ovulation date.
Conception is the condition within the body when the man?s sperm fertilizes a woman?s egg. The sperm and egg join in the fallopian tube to form a zygote, which develops into an embryo and eventually, it would become a fetus. Only if the fertilization of the egg is followed by an implantation, pregnancy will take place. Approximately, 7-10 days the zygote becomes a blastocyst, which is a product of approximately 100 cells. The human blastocyst implants in the woman?s uterus. The implanted blastocyst grows three germ layers. The inner layer is called mesoderm, the middle layer is the exoderm and the outermost layer is the endoderm. At this period of development the genetic father is completely involved into the formation of the embryo. Twin pregnancy is possible only till this stage in development.
