I hate threads like this.
Op doesn't want to breastfeed. Op doesn't want to be bullied into it by midwives etc. (those of you saying you won't be bullied into it - some midwives are quite forceful about it, they can't make you do it but I do feel some people get guilt tripped into it by midwives!)
Why is half the advice 'why don't you give the colostrum' - she doesn't want to bloody breastfeed.
Op as you've said you might change your mind, but if you don't then all I can suggest is just be firm in your answer when they ask you. Don't say maybe or I'll try the first feed, if you don't want to try it simply say no I will be formula/bottle feeding.
A lot of people on here woo tell you bf is the best thing ever why don't you just try it's the best choice bla bla but an uncomfortable unhappy mother is no use to ornament to any baby. Do what makes you feel most comfortable.
I'm not usually a 'your baby your choice hun' type person, but at the end of the day they're your boobs and you can do what the bloody hell you want (or don't want!) with them regardless of anyone else's opinion.
If you do change your mind and fancy a go, don't feel guilty if you don't like it or It doesn't work out. It really isn't for everyone imo.
