Put into stock that attempting to use Birth control pills to transition on will accomplish little if anything in terms of useful progress. They are scientifically worthless in terms of accomplishing any visable changes to your body, not enough estragen to be of any value at all, so NO, they will not accomplish any gain for you you other then open you up to undesirable side effects that you would not want. There are many reasons why you should see a doctor and get a perscription of your own. If you are not willing to do this than perhaps it is not something you should be trying to do.
