Symptoms fading?

I am 7wk5days today and my symptoms are fading. I had been having horrible morning sickness for the past couple weeks then Thursday night it was like a light switch went off and I have been feeling completely fine. Even my boobs don't feel as sore as they were. I know it is "normal" for symptoms to come and go but do they go for days at a time? I'm so scared, I've had 2 miscarriages in the past year and my last mc the first thing I noticed was my symptoms fading. We saw baby and heartbeat at 6wk4 but my next scan isn't until the 29th ;/ I am also taking progesterone which I read can prolong the pregnancy even if it has stopped..idk I am just so nervous. As much as I hated the morning sickness, it was so reassuring. Would I be absolutely crazy to go and have a private scan done? Although I'm not sure they would even be able to tell me anything.
