Tender breasts?🍈🍈

So lately I’ve been day breastfeeding and night bottle feeding. My milk supply has came in but I feel like after every feeding or pumping session my breast still feel full and tender. Is this normal? They are not warm, I did a pumping session where barely anything came out and I was on the pump for 15 mins. After I removed my breast it was still firm...

I’m a little confused and don’t know what to do😓
