Is this normal?

I am 9 + 6 with twins (we just found out yesterday at first scan), yay! Both babies were right on schedule as far as growth and moving around. My only fear (as this is my first pregnancy) is my breast soreness has started to decrease. I’ve had very few symptoms throughout this pregnancy and breast/nipple soreness was one other than some mild nausea. We go back today to see the babies and determine what type of twins but need some reassurance that symptoms fading is normal at this point. Thanks in advance!
