7w4d - Symptoms have gone away.

I know some people have said it's normal but has anyone personally experienced it? I've had nausea, sore breasts, bloating, and small cramping off and on for weeks. Today, I only have sore breasts. I have my first ultrasound Monday but I'm a nervous wreck. My last pregnancy ended in miscarriage at 9 weeks so every little thing makes me worry.
