[|Human|] Hi , I m 17 years old. Me and my bf had sex on Saturday we used protection. Afterward I gave him oral till he came then about 20 mins after he came , he inserted his penis in me for about 8 second then took it out . What are my chance of getting pregnant ?
[|AI|]  It is unlikely that you got pregnant if he did not ejaculate inside you.  However, it is possible that some semen was left on his penis.  Although I think it is very unlikely that you got pregnant, you might consider taking a morning after pill just to make sure.  These are available without a prescription from a pharmacy, and they are very effective in preventing pregnancy as long as you take the medicine within 3 days after having sex.  It is great that you used a condom, and you always should to protect yourself from unwanted pregnancy and STDs.  However, you should also talk to your doctor about starting a reliable form of birth control so you don't have to worry about pregnancy at this time in your life.
