Pregnancy Symptoms

So, I miscarried in March and am now pregnant again and 7w4d along 🌈. With the first pregnancy, my boobs increased in size and became super sore before I even had a positive pregnancy test. I was also tired and bloated. This time around, I'm tired, bloated, get headaches...but my boobs haven't gotten bigger nor are they sore. There have been changes like darkening areolas, but they haven't grown like they did the first pregnancy. Has anyone else experienced this? I know every pregnancy is different, but I'm feeling overly anxious since we lost our first baby.
