Symptoms have disappeared

Je
I had nausea, frequent urination, tender breasts, bloating, and fatigue in weeks 7 & 8. I threw up one night at the end of week 8 and since the following day my symptoms have been disappearing. I'm so nervous as I had a miscarriage in June and I want to prepare for the worst if that is what might be happening. I go for an ultrasound Monday to find out. I would really appreciate your feedback- good or bad. Thanks!
