Loss of symptoms

I'm almost 10 weeks (1st pregnancy) and suddenly have lost pregnancy symptoms. I had breast tenderness from the moment I found out I was pregnant, now nothing. I never really had vomiting morning sickness just nausea but now that seems to have subsided too. I don't have any cramping or spotting but it's weird that now I feel nothing. I fear miscarriage, am I overracting??? My next appt. is Nov 19th.
