2nd MC and last Chemical pregnancy. Anyone else had the same experience ?

Andora
In sept. I had a natural miscarriage and last night in the emergencies there told me that I have a chemical pregnancy. I didn't even know that somethings like this exiciting. 
With this there let us alone and with any explication. Just you can go home. I feel lost. Who had same or similar experience and can help me? What to do next? How long to wait for next try?
