Silent miscarriages are generally those which do not show any signs and symptoms and therefore silent miscarriage are also considered as missed miscarriage. Some women stop experiencing pregnancy symptoms like fatigue or nausea while others experience brownish vaginal discharge. Fertility doctors get to know about silent miscarriages when ultrasounds show no fetal heartbeat.
I also faced this type of miscarriage. I did not find any type of symptoms, but then it was much difficult for me to handle. I came to know about it when I visited my infertility specialist. It was a very painful experience. You need to keep patience and try for another one.
