If a miscarriage happens during the 1st trimester of pregnancy, it's usually caused by problems with the foetus. About 3 in every 4 miscarriages happen during this period..This statistics is very sad indeed, our tiny beans face the hugest issues during this very period of time. If a miscarriage happens after the first trimester of pregnancy, it may be the result of things like an underlying health condition in the mother.
Late miscarriages may also be caused by an infection around the baby. This usually leads to the bag of waters breaking before any pain or bleeding. Sometimes they can be caused by the neck of the womb opening too soon. First trimester miscarriages are often caused by problems with the chromosomes of the foetus. Chromosome problems - Chromosomes are blocks of DNA. They contain a detailed set of instructions that control a wide range of factors, from how the cells of the body develop to what colour eyes a baby will have. Sometimes something can go wrong at the point of conception and the foetus receives too many or not enough chromosomes. The reasons for this are often unclear, but it means the foetus won't be able to develop normally, resulting in a miscarriage. This is very unlikely to recur. It doesn't necessarily mean there's any problem with you or your partner. Placental problems. The placenta is the organ linking the mother's blood supply to her baby's. If there's a problem with the development of the placenta, it can also lead to a miscarriage.
Several long-term (chronic) health conditions can increase your risk of having a miscarriage in the second trimester, especially if they’re not treated or well controlled.. Infections. Food poisoning. Medicines - to be sure a medicine is safe in pregnancy, always check with your doctor, midwife or pharmacist before taking it. Womb structure. PCOS. Weakened cervix, others.
