marriage after filing N-400

I am about to file my N-400 to apply for US citizenship. Can anyone tell me how long the entire process will take? Also, I may get married after filing N-400 move to another state. Since Form N-400 asks marriage status and spouse infomation, will my marriage after filing N-400 and address change affect my application for citizenship or the time to process my application?

Any info will be greatly appreciated. Thank you in advance.
