There is chance of pregnancy because pre-cum may enter into vagina unknowingly and contain sufficient sperm concentration. So if you had sex in fertile phase of period then take I pill to prevent pregnancy. I pill cause tolerable side effect and no serious side effect will occur. It causes sometime bloating, delayed period by 1 to 2 weeks, earlier period, excessive bleeding, nausea, headache. Avoid stress, take healthy diet, Chat Doctor.  Use condoms in future to prevent unwanted pregnancy. Hope this may help you. Contact further if follow up needed. Best regards, </s>
