<s>[INST] Hi doctor!my question is -I am 28 yrs women. Married. We have unprotected sex on 18th August. &I take I pill.but I have vomiting in half hour after taking ipill. But now we want to take chance for baby. So can we plan for pregnancy now. My LMP is 6th August. How long effect of ipill ? [/INST] Hallow Dear, Since you have vomited out within half an hour of consuming I-pill, the pill should have been expelled out in the vomitus. So this pill will not give you any protection from the pregnancy. Of course, pregnancy also is not guaranteed; however, you had unprotected sexual contact around the day of ovulation and in the fertile period. So there are good chances of pregnancy. To find out whether you are pregnant or not; you have following options: 1. Perform Beta hCG test on your blood any time after 28th August. 2. Alternatively, wait for your menses to appear. If they appear, you are not pregnant. If they are delayed, wait for  a week and then perform pregnancy test on overnight morning first urine sample; earlier the test may report false negative results. Since the pill has been expelled out within half an hour of ingestion, it does not have any effect on the body as it was not absorbed at all. So there is no risk to the pregnancy if you are pregnant. I hope this clarifies your doubts. Dr. Nishikant Shrotri </s>
