Is Miscarriage Scary?

Went doc yesterday and confirmed that my sac is empty with yolk nd is only 5 week pregnant. Now is waiting for my body to have the discharge naturally. I do not know when is going to happen and I started to have a little brown discharge and after that no more. I'm not too sure if need confinement for 14 days? What should I do or buy? What it going to happen to me? I'm clueless and lost. I will cried when my mum and hub console me and couldn't control my emotional and tears.
