Miscarriage is very common it will occur in 1 out 6 pregnancies. Usually most miscarriage happens during the first 12 weeks of pregnancy although it also occurs up to 20-24 weeks of pregnancy before most evolving babies in the uterus are capable of surviving outside the womb or uterus.  However, a woman's physical experience of it differs from another woman's experienced. The loss of pregnancy can be hard to accept but it helps to know that it doesn't signify that a woman will not have pregnancies because a greater majority of women have successful pregnancies, again.

In all miscarriages, about 50% of it happens because of genetic material problems like the way chromosomes joined when the egg of a woman and a man's sperm has combined during fertilization. A woman may not ever find what has transpired, but most likely it is due to unintended problems either in you or in your partner. Often you won't even know what caused the miscarriage and there is very little that can be done to prevent it from happening again. Contributing factors in miscarriage are usually the disparities in pregnancy hormones, your immunity system problems, infectious disease such as listeria infection cause by a bacterium of the genus and exposure to dangerous chemicals such as benzene, formaldehyde and arsenic before or during pregnancy.  Moderate exercise or sex during pregnancies doesn't increase the risk of miscarriage, but miscarriage developed more commonly as the woman get older primarily due to a decrease in quality of the eggs as you aged.

There are several miscarriage symptoms that will occur during pregnancies. The most common is vaginal bleeding. This varies from light to heavy spotting, constant or irregular that is heavier than your period. You can often get pelvis cramping, dull pain at the back, breast tenderness, feeling sickly and urinating more frequently than usual and the passage of unidentifiable tissues resembling large thick blood clots. Sometimes symptoms can only be discovered during your routine scan.

A little bit of bleeding without the cramping in the pelvis area should be alright. Darting small cramps, even if they hurts may just a signal to the body stretching that usually occur to accommodate the growing baby. You may just lie down and it will just go away in an hour. However, if you're unsure you are pregnant, these symptoms can be other symptoms other than a loss of pregnancy, but nevertheless see your doctor.

But most of it all, if you have vaginal bleeding at any time of your pregnancy, you should immediately see your doctor or midwife for an advice.
