First month of pregnancy
It is the first month after you have become pregnancy and feeling it in your womb. After the sperm penetrates the egg to complete the genetic makeup of human fetus, three days later the fertilized egg cell divides rapidly and then passes through the Fallopian tube into the uterus, where it attaches to the uterine wall. Fetus gets the nourishment from the attachment and soon forms placenta. After this stage, your baby becomes an embryo consisting of two layers of cells from which all her organs and body parts will develop.
