I ddn't have any pg symptoms at all through my whole pregnancy. I only got braxton hicks the day before my waters broke so please don't let it worry you too much. I know it plays on your mind but try toenjoy your symptom free pg cause you never know when your symptoms might start.
I also got completely jibbed on the big bb's too. I was so excited that I might get big bb's. But nope. When I was pg they didn't change and everyone said just wait til your milk comes in but once again they are certainly not much bigger then it was wait until you establish b/f but no!! Completely ripped off.
