Boobs?

Zerenity • 28. Arizonan. Army Wife 💍
My boyfriend told me that I've gained a little bit of weight which I have (8lbs) and that he's noticed my boobs have grown but my nipples look like the color after I've had a child. I'm 22 and never been pregnant nor am I pregnant. Is this normal for them to look like that? Just a little worried.
