I'm 9 weeks 4 days today and

I just bawled due to the fact all my symptoms seem to have lessened drastically. All I've really had is sore sore boobs and being tired. But even my boobs don't hurt today. Am I being crazy? I still have 9 days until my first appointment. My doctor seems to think it's fine and it could just be me leveling out. I Why do I feel this way? This is my second baby and I'm absolutely just terrified. All I keep reading about is missed miscarriages. I know I shouldn't read up on this stuff but I can't help it. :(
