<s>[INST] i had unprotected sex and took the morning after period. I had more unprotected sex after that, we were using the withdrawal method. At my estimated menstrual period time, i got all the symptoms-cramps, tender breasts, pimples etc but very little blood quite unusual as i usually have a very heavy flow. Could i be pregnant? [/INST] HiI can understand your concern for the delayed period following unprotected sex.Delayed period following unprotected sex and symptoms like cramps, breasts tenderness, pimples are suggestive of an early pregnancy.Withdrawal method is not an effective form of birth control. Sperms can enter the vagina if withdrawal isn not properly timed or if pre-ejaculation fluid contains sperm. Of every 100 women whose partners use withdrawal, 4 will become pregnant each year if they always do it correctly. Of every 100 women whose partners use withdrawal, 27 will become pregnant each year if they do not always do it correctly.    Pregnancy is also possible if semen or pre-ejaculate is spilled on the vulva.So, I advise you to get the pregnancy test done on an early morning urine sample and consult a gynecologist.Hope this answers your query. </s>
