5w5d lost symptoms

Essco
Recently I had all the normal pregnancy symptoms sore breasts, cramping, frequent bathroom visits. I went in for an ultra sound two days ago due to some discharge with white specks in it. I was thinking maybe I had a infection, well they're going to call back today with results but I've also noticed my breasts are not sore anymore and I really don't feel pregnant anymore  aside from some nausea. Has anyone had this happen where the symptoms come and go? I thought this happened later in pregnancy when everything balanced out and your body got use to the changes. I had a miscarriage a year ago so I'm worried this time around. The doctor doesn't wanna see me again until 8 weeks and I'm going crazy with worry.
