If the players you're playing have close to the same ratings as each other, your rating very possibly could not change, considering a provisional rating is simply calculated by averageing your opponent's ratings (+400 for a win, -400 for a loss and no change for a draw). So even if your opponent's rating is very close to the current average of your opponent's ratings, it very possibly could not change your rating even by 1.
