Yes its possible you could conceive. Take Plan B.
If your idea of birth control is an abortion then maybe, otherwise no.
Yes, you can get pregnant and be on the pill. The pill is not 100% effective and therefore it is possible. You cannot "stop" a pregnancy. Your only option would be an abortion or to carry full term. Either way if you are pregnant you should stop taking your birth control right away.
Taking birth control is the key here. As long as you have not missed taking any of the BCP you are 99.5% protected from pregnancy.
By using birth control or not have vaginal intercourse. If you already are pregnant (you formed the question a bit strange) the only way to terminate a pregnancy is by having an abortion at the doctor.
There's a chance. You should probably go see a doctor and/or get a pregnancy test. Also, if you're not pregnant, you should consider carrying a condom/ start using the pill. Assuming you're not trying to get pregnant ofcource.
Yes.
According to the Mayo clinic nothing happens. If you are aiming for an abortion you have to see a doctor. Birth control pills can not make you abort. They can be used as morning after pills within 5 days after sex but not once you are pregnant.
Abortion
If you are no more than 9 week you can have a medical or suction abortion. Passed that it has to be done by surgery. See your doctor. That is the only legal and safe way.
You're not pregnant. Same thing happened to me :) im 16. Biggest scare of my life but no you're not pregnant.
No, that is birth control which prevents pregnancy. it can not terminate it. And you can not know if you are pregnant until at least 2 weeks after sex. If you want an abortion you have to see a Gynecologist and if you have no safe abortion provider around you can find one on a safe site like womenonweb.
The abortion pill works up to the 9th week. No other pill works. If you mean the birth control pill or morning after pill, it will not work as soon as you are pregnant.
