Hi, My wife gets periods regularly every 28 days. We work in 2 diff cities and meet on weekends & holidays. Last time we had unprotected sex. She got her periods on 6th of June and we had unprotected sex on the following weekend that is on 12th & 13th of June & as we were worried of any unwated pregnancy we had used i-Pill on 13th afternoon. Now she missed her periods by 2days. Though we are aware that i-Pill may delay periods, still I thought of seeking your advice. I will be meeting my wife comming weekend. Kindly advise me accordingly if I had to get her some medication to prevent pregnancy. Are the one-step-pregnancy-test-kits reliable if we opt for them. Thanks & Regards, Shan

Hello dear, I understand your concern. In my opinion the delay in period might be due to pill. Usually pill is 95% effective if taken within 72 hours of unprotected intercourse. As you have taken within stipulated time the failure chance is rare. As the pill is a high dose progesterone the timing and amount of bleeding of period can be effected. So the pill might have delayed the period. Just to clear the benefit of doubt I suggest you to do a urine pregnancy test. The test is usually positive a week after missed period. I suggest you to wait for spontaneous onset of periods. But overall the chances of pregnancy are very, very rare. The one touch urine pregnancy tests are reliable. And for now no medicines are required for the termination of pregnancy. Just need to wait for the periods and test for pregnancy. Hope this helps. Best regards...
