Not everybody gets these little nodules, or skin tags, but they are not uncommon. I got them in my first pregnancy, but not in the 2nd or 3rd. It's quite normal, it's just hormones doing weird things to your skin.

The darkening of the nipple and aureole (sp?) is also perfectly normal, and most women WILL experience this. The aureole will probably continue to grow as your pregnancy progresses, I have seen women who have it covering 50% of their breast whilst breastfeeding - although it is unlikely that you will end up with that much colour! It does gradually go away again after you stop b/f, although your bbs will never be quite the same again.
