in need of some advice....

so I found out very early that I was pregnant (3w3d) right after my first cycle from my miscarriage. I have my first appointment this coming up Monday and am terrified of them telling me the baby stopped growing. currently 9w+1. had symptoms of sore breasts, slight nausea, and occasional vomiting last week. as of now I have no symptoms other than kinda sore nipples. terrified of what to do or how to feel, how can I get over this
