Nipples TMI

Debbie • 1st time mammy
Ok so while getting dry this morning after I'd been in the shower I noticed some flaky bits on my nipples. I'm 23wks and they're not sore or anything (possibly a bit dry like the rest of my skin at the mo). It was kinda like the dry bits you get In The corner of your eyes when you first wake up.
Is this normal? What is it? I just rubbed in some savlon and it seems to be ok-but I don't have a clue what is going on.
