Then you can expect to be fertile off and on - if you are sexually active you can count on getting pregnantsooner or later.
Believe it or not, it can. It all depends on how quickly stuff is moving through your system. If your birth control is going right through you and not getting absorbed, you could get pregnant.
It is not that they are getting smaller, it is that the breasts are going back to their normal size. Birth control can sometimes make the breasts swell, just like right before your period. They will not be any smaller then before birth control.

yes very much so, unless you want to become a parent, then birth control is going to get in the way...
If you're not on it already, try going on birth control. It happens to many women when they first start on birth control that your breasts may go up a full size. If you are already on birth control, try going on another one. The difference between the two sometimes has the same reaction from your body as first going on birth control does. But if you are changing birth controls, or are going on it the first time, make consider your options and make sure with your doctor which one is the best for you.
No. There is no correlation whatsoever between me taking birth control and you doing whatever it is you consider doing.
How long it is going for what? Missing birth controls like you have will put you at risk of pregnancy. If your trying to conceive then stop taking birth control because this will harm the Foetus when you do conceive.
It all depends on how long you bled before you got on birth control. Some birth control pills stop bleeding completely. If you want to know specifics your going to have to talk to your doctor.

Tampons usually work, though if you are under the age acceptable for using tampons you can use a pad and a one-piece bathing suit. It works, I've tried it.
No. No school can make anyone use birth control.
