A miscarriage could be brought about by a variety of issues prior to, during or following the process of fertilization (when the sperm and egg join). Almost all factors that contribute to a miscarriage are genetic in nature. Occasionally a miscarriage is attributable to a health issue. Frequently though, no specific reason for a miscarriage can be named.

Miscarriages appear in approximately 15 -20% of pregnancies. Most happen during the first thirteen weeks of pregnancy. A number of miscarriages take place in advance of a woman missing a menstrual period or before she is even knows that she is pregnant. Greater than one half of all miscarriages within the first 13 weeks are due to problems with the fetus’s chromosomes. Miscarriages can stem from an irregular number or composition of chromosomes. The majority of chromosome complications are not inherited. They materialize by chance and are unlikely to happen again during a later pregnancy. In most instances, there won’t be anything wrong with the woman’s or man’s health. The possibility for these complications goes up with the age of the woman.

Infections can alter the uterus and fetus and, consequently, terminate the pregnancy. Complications with the woman’s hormones may also result in a really early miscarriage. Should the woman have a chronic disease, like diabetes which isn’t managed, she might have a greater chance of miscarriage. Issues with the uterus or cervix could also result in miscarriage. Issues can include an irregular shaped uterus or an incompetent cervix. An incompetent cervix starts to widen and open prematurely, generally at 14-26 weeks, with no pain or any other indications of labor.

Pregnant women who smoke are more inclined to experience vaginal bleeding while being pregnant. The likelihood of miscarriage is greater than that of non-smoking women. Significant alcohol consumption and illegal drug use also multiply the chances of a miscarriage. This is particularly true at the beginning of pregnancy.

Bleeding is the most frequent indication of a miscarriage. The majority of women who experience vaginal spotting or bleeding in the early months of pregnancy deliver healthy babies. A number of these women, however, will have a miscarriage. Bleeding in the course of early pregnancy is known as threatened miscarriage. At times minor cramping in the lower abdomen and a lower backache may develop in addition to the bleeding. Bleeding can last a while, grow to be heavy or appear together with a menstrual cramp like pain.
