Although you will have immediate protection if you start the new Birth Control pill on time, it may take a month or two for your body to fully be adjusted to the new birth control.
You could get side effects for about 3 months. Your body just needs time to adjust. If they persist after that, you made need to switch your brands of birth control.
You can switch forms of birth control to what is most comfortable for you. If you would like to switch birth control consult your physician so that she/he can choose a birth control pill that is right for you.

Yes birth control changes your cycle causing your body to have to adjust to the birth control after a few weeks it should become a normal schedule.
Birth control is what is used to prevent unintended pregnancy, there are multiple different types of birth control that work in different ways, it is ignorant to say 'birth control' to mean one specific type of birth control. Without knowing what type of birth control you're referring to we cannot answer your question - some birth control does absolutely nothing to your hormones, some birth control completely shuts down your hormones.
Some different forms of birth control includes birth control pills, morning-after pills, condoms, diaphragms, vasectomy for men, and sterilization for women.
When you switch brands of birth control to a generic, you are still getting the same hormones and the same dosage of hormones, the only difference is that the pills were made by different companies. If you have been on birth control for at least 2 months, it is still safe to have unprotected intercourse even though you are switching birth control. If you haven't been on birth control for at least 2 months you should use a back-up method, such as condoms, during the first week of starting your new birth control. If you want to be even safer, you could wait 2 weeks to have unprotected sex.

No, birth control is exactly the same if you've already had sex or not.
Yes, you can change to a different method of birth control. You can have the copper IUD inserted at anytime, and can start a different hormonal method of birth control after ten weeks.

It is definitely safer to switch from the birth control to the shot, as you have protection throughout. If a woman on the birth control pill gets a Depo Provera injection, she will have immediate protection against pregnancy. If a woman not on birth control pills gets a Depo Provera injection, she may have a delay in protection, depending on where she was in her menstrual cycle.
