If you breastfeed then they will stay this way until you wean, but otherwise they will return to normal shortly after pregnancy.
Yes most likely they'll go away, BUT I've nursed two of my four babies so my nipples never relax now!!! If i have my bra off it looks like I'm constantly cold, soooooo embarrassing!
Yeah it go away after you have your baby.. They get darker n bigger but it doesn't stay that way lol
