Depends on what pills you are talking about. For any pill that prevents pregnancy, or end pregnancy, there are instructions or prescription to follow.
I am not sure what you mean by cancel out a pregnancy. The only way to stop a pregnancy once it occurs is abortion. Sometimes you can induce a period before pregnancy occurs to prevent it. The pills have instructions that say exactly how many you can miss.
The while pills on Trinessa are active pills that prevent pregnancy. If you don't take the active pills, you could get pregnant.
All of them! If you are trying to get pregnant you do not want to take birth control pills. Their whole purpose is to prevent pregnancy.
The active birth control pills are the ones that prevent pregnancy. If you don't take those pills, you could get pregnant.
That would be foolish. Birth control pills prevent pregnancy.
Advil don't prevent pregnancy no matter how many you take.
Birth control pills are immediately effective when started within the first days of your period; otherwise, it's seven days before they can be relied on to prevent pregnancy. Stopping them after two weeks makes no sense, unless you never want to prevent pregnancy after that two weeks.

Yes. Birth control pills do not affect the accuracy of pregnancy tests.
No
The main reason is to have sex without getting pregnant. Some might take birth control pills because they have conditions that make pregnancy unsafe for them. For instance, they might have diabetes, heart disease, asthma, or problems with their female parts, so they take birth control pills so they won't get pregnant and risk their lives or produce deformed offspring. Some medications are so dangerous to possible offspring that doctors will make women take birth control pills with them. A few who live in dangerous locations might use birth control pills to prevent pregnancy from rape. Some people take contraceptive pills for reasons that have nothing to do with pregnancy. They may take them for skin conditions such as acne. Male to female transsexuals may also take birth control pills to help get female secondary features. If we include condoms and similar barrier devices, then the purpose is to not only prevent pregnancy, but to reduce the chances of contracting sexually transmitted diseases.
