Ever since I got pregnant everytime I get cold & my nipples get hard, they hurt so much. Like no other pain I have felt before. They legit feel like they're burning off to the point where it makes me want to cry & I don't cry easy. Any one else have this? Why does it happen? How can I help it? 😩 it hurts so bad.
