sore nipples

Katie
My nipples have been sooooo sore today. I've been emotional wreck today and yesterday. I had spotting on 1/13 which is rare for me. AF kinda due 1/22. This will be my second post pardum period (LO is 9 months old) so idk how regular it'll be. I'm trying to wait to test until Sunday incase my cycle is longer than normal. I'm going nuts. What symptoms is everyone else having?
