Well here in NY where im from it is really easy to get condoms and birth control totally confidential. Most of the time its at no cost at free clinic. I believe your chances are slim, not that you cant but that its not that common usually there only 5 days of the month where you can actually get pregnant those are the peak of your fertility and the day of ovulation. Usually it takes 14 days for normal 28 day cycle to ovulate. but being that sperm can live inside you for 3 - 5 days it can stay alive to reach the peak of your fertility. i would just relax and absolutely not have sex with out a condom again if you aren't trying to conceive. Don't over stress because to can cause you to be late on your period next month making you more anxious. Good luck hun hope all goes well.
OMG scooping sperm out will NOT make a difference! Unfortunately there is a HUGE chance of you being pregnant! Girl, there are loads of free contraception methods out there for you being provided for by the government, especially as your 16. if your in the UK, the NHS provides it for free! if you not in the UK, a condom doesn't cost a fortune! A baby however does! Take the morning after-pill straight away if the condom splits or you don't have any condoms. I hope everything goes the way YOU want it, either way because being pregnant will affect YOU more than anybody else. Take care honey, there is still a big chance of you being pregnant, look after yourself in the future.
