Yes: In above mentioned circumstances pregnancy is possible. Always use contraception and mechanical protection in order to prevent STD’s and avoid undesired pregnancy.

Yes: What you described could result in pregnancy. 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. Consider IUD or implanted contraceptive.
