<s>[INST] Hi, Long story but to make it short, I had my period on June 14 through the 18th. Never on birth control; Had sex on the 27th. Boyfriend ejaculated in me three times. Pretty much unprotected sex. (The sperm might be very strong because my boyfriend hasn t been sexually active for about 2 weeks. ) Took Plan B on the 28th. After 24 hours..What are the chances of me being pregnant? No side effects yet but my vagina is a little itchy. Please HELP! [/INST] Hi, I understand your concern. You have unprotected sex in fertile phase of period. You took plan B pill after 24 hours. It has up to 85% effective in preventing pregnancy. It has 0-15% failure rate in your case. But pill can cause earlier period, delay in period by 1 to 2 weeks and excessive bleeding can occur. I would suggest to wait for period. If period will delay by more than 2 weeks then go for urine pregnancy test and or blood Chat Doctor test to confirm pregnancy. If you will be pregnant then you can still terminate intrauterine pregnancy by abortion pill under advise of gynecologist. Meanwhile, avoid stress, take healthy diet, Chat Doctor. Hope this may help you. Contact further if follow up needed. Best regards, </s>
