Had unprotected sex on 2nd day of my period. then i got the next period after 33 days &lasted for 7 days.now my upcoming period is late &33 days has passed&it didnt come yet. can i still be pregnant? my previous cycles varied between 28 to 30 days?

Depends: If you had sex since your last period, and missed 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 carefully. Wish you good health! If you do not wish to be pregnant, use contraception all the time, every time. Consider implanted contraceptive, or IUD.
