Please read an help me!

So the past couple of days I have had a feeling something is wrong. That I have lost my baby. I'm getting more nervous by the day. I lost my baby at 8weeks 5days this last March. I'm 8weeks 3 days now and I have a terrible feeling. I have an appointment on Monday but I'm worried that I'll go in and there will not be any heartbeat again. My boobs have been sore and I have occasional nausea well had until a couple of days ago.
