10 weeks pregnant with loss of symptoms?

Hi, I'm about 10 weeks pregnant, and my next appointment isn't until January 6th. I saw a strong heartbeat at 7 weeks, which I also heard. My pregnancy symptoms are fading, the only time my hurt is when I wear a push up bra, to where before they were killing me, and swollen in the mornings. I just have a feeling that something might be wrong. I only get sick once every morning, that is just yellow stomach bile. should I call my dr.'s tomorrow, or should I wait? Could symptoms fading be normal? Am I just being paranoid?
