Pregnancy Info HOME

I was in the ER two days ago, scared i was having a miscarriage. The doc did an internal, saw there was bleeding, and said my cervix was closed.I went for an emergency ultra sound and said the heart beat was good but i still have cramping, backpain and a little spotting at times along with a brown slimy gew. Is this normal and how would you know if you miscarry. What are the tell tale signs and can you still have intercourse in this state?
