Breast changes while pregnant

My first symptom of pregnancy was very very sore breasts, tender and they were growing. I’m only a few weeks away of birth and I noticed for the past probably 2 or 3 months they aren’t as tender or sore. Only my nipples are sore sometimes but not even a lot anymore. But they aren’t tender and everyday I feel like they only get heavier but also they are just very “bouncy” (lol sorry I don’t know how to word it) they just aren’t tender and just feel like water balloons.. is this normal to not be tender anymore
