Hallow Dear, You have very rightly taken a precautionary step of taking I-pill. Though he did not ejaculate in the vagina, the chances of depositing Pre-ejaculatory secretions in the vagina or on the vaginal outlet are very high. Moreover, depositing the semen on the vaginal opening is sufficient for the sperms to enter in to the vagina to cause conception. I-pill has to be taken within 72 hours of unprotected sex. You have taken it within 40 hours. So you are well protected. I-pill is a Levonorgestrel (Progesterone) preparation. Hence few days after its consumption, some withdrawal bleeding can take place. The bleeding you got about 2 weeks after menses was this withdrawal bleeding due to I-pill. Subsequent periods after that may get delayed. So if you are delayed by few days, you need not worry. However, if the periods are delayed for more than a week, you may perform pregnancy test on overnight first morning urine sample for finding out the status of pregnancy. Alternatively you nay opt for Beta hCG test. The probability of pregnancy is very remote; still if you do not get menses in spite on no pregnancy , you may take Tab. Deviry for 5 days and you will get withdrawal bleeding after 4-7 days. I hope this helps you. Dr. Nishikant
