is this ok to do?

So I have a two week old now and I've contemplated breast feeding. I have many reasons as to why I do and don't want to breast feed which I will not get into. Anyways, I am still producing milk and am wondering would it be bad to give it a try one time? And either if I find I'm comfortable with it and like it, stick to it and both breast feeding and formula OR if I decide I'm not into it to just never try again? I'm just not sure if it's ok to do or if she'll get hooked from one try.
