<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor... my room mate is worried because she had unprotected sex twice on 221216 and ejaculation happened in her vagina. But she took I pill on the same dayafter10hours. And her period is due on 6117. Is there any chance she can get pregnant?  <response>: Hello, I have gone through the query and understood your concern. Your friend had the intercourse during the fertile or ovulation period and as a result, her chances of conception are high. Yet, since she has taken the emergency pill soon after, she is 80-85 percent protected. She may expect some with Chat Doctor. Her next natural period also may get delayed by a week or two because the emergency pill contains high dose of progesterone. If she becomes overdue by ten days, she has to see a gynecologist for further management. She would then need to exclude pregnancy and go for a trans-vaginalpelvic sonogram before a period is induced if pregnancy is negative. Please note that emergency pills should be used only for a couple of occasions a year and regular contraception is preferred to prevent accidents. Hope this helps.
