Symptoms disappeared at 6weeks

Pre

I was very nauseous and had pain in breast while I was just under 6 weeks. Suddenly my nausea has reduced and pain in breast disappeared since 2-3 days.

Is that normal and likely to come back or should I prepare myself for bad news(hope not)

My 1st scan is on 7w1d so in 4 days time and I'm so nervous with these disappearing symptoms
