Symptoms Going Away?

AB

I'm 8 weeks pregnant. My first symptoms were crazy heartburn, sore boobs, and very light cramps. Then I got the fatigue and food aversions. But now, my symptoms are going away. My boobs are less sore. I'm not as fatigued. I don't have as much heartburn. Should I be worried? I have my first appointment next week, but am scared I've had a missed miscarriage.
