it's better if you vary your workouts. that way, you won't be as susceptible to hitting a plateau. those who go in and do their 3 sets of 10 all of the time are the ones who stop moving forward and then wonder why. so, do what you feel like. always listen to your body. if you've got a coupla more reps today, then pull them off. can't quite get to the 15th rep? it's ok, because you are listening to your body.

trust me, you've got a lot to be proud of already. you actually make it to the gym to workout. perfect form is better than too much weight, too. if you start to get sloppy you might get muscles involved in the action that you never thought could. listen to your body, keep perfect form and workout how you like. you'll never do damage to yourself that way.
