Pregnancy symptoms disappearing

Aimie

6 weeks 3 days, I have noticed on Thursday my symptoms starting to become less and less. My boobs aren’t hurting, no real nausea and not feeling tired like I had been. The only thing I’m having is very light pelvic ache which I have had the whole time. I’m terrified I am having a missed miscarriage. We go to the doctor on Tuesday for our 1st US. Has anyone else experienced this and it been normal?
