Sore boobs? (TMI warning)

Okay, this is new. I've had very sore nipples for the last 4 days. Nothing else is sore, just my nipples. This fact amuses my other half and he thinks it's funny to try and touch them at any point in time. I'm also peeing like a racehorse. Yet, I still don't feel hopeful because my temperature has begun dropping. Ugh! 5 more days until testing.
