symptom gone at 9 weeks

I’ve had a pretty smooth first trimester with minimal symptoms (and everything looking perfectly fine) but my biggest symptom was sore breast. For the past couple of days i’ve realized my breast aren’t as sore as they use to be and I was wondering if it was normal for symptoms to start disappearing around this time? I’ve read once you get into the second trimester they start lessening but what about 9 weeks? :)
