Posting one more time

Okay so I just need peace of mind. I have my first appointment Friday.. however, my boobs are sore but not as sore as they used to be. I have some nauseous points but not consistent or every day. I googled it and they said that basically if they go away fully then you’re probably going to miscarry. And that terrifies me. This is my third pregnancy. I remember having symptoms with my last two but don’t remember when I got them and if they came and went. Did that happen to anyone else where it was sore but not as sore the next day? And everything be just fine? I’m 5 weeks & 2 days.
