7 wks and suddenly feeling better?

Hey ladies, I need some advice! 
I just hit 7 weeks yesterday and all of a sudden am no longer nauseous, exhausted, and my boobs aren't hurting as much anymore. Has this happened to anyone else?? Last time I was pregnant I miscarried at 7 weeks, so this just makes me a little anxious. I am thinking all is good so far because there is no bleeding, but I have to wait until next Friday to see the doctor for the first time. Has anyone else experienced this?? Any advice is greatly appreciated!! Thank you in advance!
