Question

about one third of fertilized eggs fail to implant in the uterus and are lost. an imperfection in the amount of genetic material can also cause the embryo (the very early stage of life) to be lost soon after implantation. but this can occur even before the first missed period, so that a woman will not even have known that she was pregnant.
a miscarriage is the \spontaneous loss of a pregnancy before the fetus is 20 weeks old.\ (www.onlyhealth.com) it is also known as spontaneous or natural abortion. a woman is likely to experience cramping followed by heavy blood flow as the fetus and lining exit the woman’s body.
after 20 weeks, a pregnancy loss is considered a pre - term delivery.
full gestation (development) is considered to be between 37 - 40 weeks (more often 40). after 42, you are overdue!
