I am not sure: But you can always be pregnant even though you take precautions. So... You need to see your doc if you think you are.

Contraception.: If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex have HPV vaccine.
