<s>[INST] Hi doctor, I had last sex 6 days back and I had I pill in next 60 hours first a fall I would like to know what are the chances of getting pregnant ? My next question is after sex n eating I pill my stomach start paining badly n I caught uti. Please suggest me some cautions for uti. [/INST] Hi and welcome to Chat Doctor. I pill taken within 72 hours of sex is effective. The sooner you take i-pill, the more effective it is. i-pill is 95% effective within 24 hours of unprotected sex, 85% between 25-48 hours and 58% if taken between 49-72 hours, so their may be chances of pregnancy. Nausea, vomiting and headache are some common side effects after taking i-pill. You might also have some lower abdominal pain or find your breasts more tender than usual. All this should stop within a day or two. You are having these side effects, and it will subside. It might also cause your next period to come early or later than normal. But if your periods are delayed by more than a week, you should go in for a pregnancy test and contact your doctor. I advise you to consult a local doctor if pain continues for long duration, and it is always safe to use condom rather than any emergency pills. Hope this answer helped you. Regards Chat Doctor.  </s>
