I want get my wife pregnant but on birth control shot how can I get her pregnant now?

Moved to its own question. These are not blogs, you must write your own question. If you wish to give follow up info, please answer your own question.

Does you wife want to get pregnant ?

What type of birth control is she on

Have you discussed this with her doctor?

This is definitely something your wife needs to be involved in. the fact that you say she is on birth control makes me wonder if she actually wants you to be getting her pregnant. And if she is on birth control then it's not likely for her to become pregnant as long as she is on it, since that's the whole point of birth control, to prevent pregnancy.
