7 weeks 4 days

There are days when I feel sick to my stomach off and on. There are days when I am bloated and have upper abdominal pressure. But...there are says when I feel fine and don't feel pregnant at all. My doctors appointment is not until October 10....by then, I will be 11 weeks. Its hard having to wait that long and I am scared something will happen before my appointment...or scared I'll go to my appointment and I will have lost the baby. Is it normal to have symptoms only sometimes?? I called the doctors office with some questions and there answer was "its a waiting game" until my appointment.
