It is hard for me yo tell as I was still nursing when I got pregnant,although I think they are slightly darker.I dont think everyones change, just like some women dont get the linea nigra.
Mine turned darker at 7 weeks into my pregnancy, and have turned even darker as my pregnancy has progressed.
I don't know when mine turned. Like jscoch said, it was gradual. They might still be getting darker. They changed with all my kids but I don' think it's the same with everyone.
hmm everyone I know that has had a kid turned brown. I was just curious when it usually happened. Maybe I wont have any change then.
mine have been darker for quite awhile - it was so gradual i didnt really notice when it started
I never had any color change, and I was full term and nursed for 18 months.
