Early Pregnancy Symptoms Disappearing?

Hey, ladies! So, I was wondering if this has happened to anyone else... since I found out I was pregnant, I immediately started having vveerryyyy tender breasts, extreme fatigue, mild cramping, and intermittent nausea. I'm 5 weeks and 5 days, and since yesterday I have had hardly any symptoms at all. Yesterday, I just woke up and my boobs felt fine and I had zero nausea or cramping. Today, my breasts have been a little sore (I think because yesterday I kept messing with them to see if they would start to hurt again), and no other symptoms. I read online this could be signs of miscarriage, or possibly nothing. I just worry that having symptoms disappear so early in pregnacy can't be a good sign. I thought about calling my doctor, but I have an appointment in 2 days and figured that's the soonest I could get in anyway. But I would love to hear if anyone has had anything similar happen to them and what the outcome was!
