Early signs of miscarriage in first trimester

first trimester miscarriages that has not symptoms are missed miscarriages. you won't know until you get the scan. I had 2 missed miscarriages before I had my first born. There's nothing to be done to prevent it. Sometimes it is because the pregnancy is not viable. It is actually quite common. Just that people don't talk about it. I'm now in 3rd trimester for my second. Just be positive. Try not to feel stress or have negative thoughts.
