Bridget • Ttc number 9 and just got my bfp due 12-1-16
The doctor told me last week that my 7 week old fetus heart stopped beating and tonight I finally started getting cramping and a lot of mucus with pink in it. Is this normal and what should happen next? I have never had one and I'm so scared what I might feel or see. Please help
