Hi, Thank you for posting your question here I will try to answer it to the best of my abilities. Yes, there is a possibility of getting pregnant if you miss your contraceptive pill and have unprotected sex. Wait around 7-10 days and then take a home pregnancy test, that should give you your result. Alternatively you can go to a doctor and ask him to test your blood to check if you are pregnant. Another thing you can do is call up your doctor and ask them to prescribe you with emergency pills that work for up to 5 days after unprotected sex, for example ulipristal acetate. So if it has been less than 5 days since the incident, I believe that would be the best option for you. I hope this answered your question.
