Not likely, but: Not impossible. Wait until your period would be due normally and, if it does not arrive in a few days, do a test - at home or at a clinic/doctors. While there you could get good info on how to protect yourself from both pregnancy and STDs. You can also learn about the early signs of pregnancy, etc. As you become a responsible, sexually active, mature adult, these should all be part of it. Best!
