You can't really see mine and I'm 34 weeks my nipples also didn't darken. Everyones different so don't think something is wrong.
Ugh mine are awful. I'm almost 25 weeks and I swear I think I see every single vein I have in my boobs. If you don't have them yet enjoy it because I promise they are not pretty. Lol
