Since it may take weeks for this to happen, it requires close consultation between the patient and her health care provider. The most common, by far, is a chromosomal abnormality where the genetic material from the sperm and egg do not fuse together appropriately. For this reason the overwhelming majority of doctors do not advise a complex evaluation after a single, first-trimester miscarriage. However, consecutive miscarriages, and especially pregnancy losses that occur later in pregnancy, often need a thorough evaluation. Couples need to realize that they did not do anything wrong that may have caused a miscarriage.
Miscarriage is a devastating situation that is only made worse by unnecessary guilt.
Sexual activity, exercise, a normal diet, bathing, swimming, and working in a reasonably normal job have never been significantly linked to pregnancy losses. In this situation the uterine muscle is slightly malformed and the pregnancy cannot grow appropriately. This problem is diagnosed with a special x-ray or ultrasound of the uterus and surgery to correct the defective area is usually successful in curing the problem. Some unusual vaginal infections can cause recurrent miscarriages, although it appears that this is not common. Cultures of the vagina and antibiotics are sometimes helpful if your doctor suspects an infection.
