Sore nipples but not sore boobs?

My af is due today 4/3 but it is not here yet. I only have sore nipples but not painful sore boobs. I usually have heavy sore boobs which hurts when I take off my bra but it is different this time. I keep having small cramps and feeling "wet" like af is coming. Anyone had this and got a bfp? Should I wait or test?
