nipple tingling? labor near?

Cheyanne • ♠♎♠

So today I've felt crampy on and off and baby girl hasn't been moving quite as frequently but still enough to know that she's active...well tonight my nips have gotten hard and tingling a few times and kind of achy..anyone have any experience with that?

also a side note, earlier I was visiting a friend and her dog just kept sitting in front of me whining and she would not leave me alone lol very odd
