It depends on the type of birth control. Sometimes after starting it, it could be longer than normal, and sometimes it will disappear the first month. Sometimes it will be normal, and sometimes is will be shorter.
It is normal for everything to feel like it's working hard down there, three days after starting period for the first time, because you are not used to. If it continues that way, you should seek medical help.
There is a very small chance you may miss your first period after starting the pill, but if you don't miss any pills then you shouldn't miss your period - still it does sometimes happen. Usually though most women will experience some form a vaginal bleeding.

Yes. All of those can be symptoms of your period starting. If you think it may come soon, wear a pad in your underwear. It may start soon, or you may just get those annoying symptoms for the first few months without the actual bleeding.
This is not exactly normal but it does sometimes occur when you first start BCP. Because of this I wouldn't worry too much but if the same thing happens next month then see your Doctor.
