I took an ipill on 10th august morning within 10 hours of intercourse but didn't got any sort of withdrawal bleeding . kindly tell if it is necessary to have . my last cycle was from 31st july to 3rd august . please please reply and suggest?

Plan B is about 95% effective in preventing pregnancy. Plan B (ipill) does alter hormonal balance but does not always result in withdrawal bleeding. If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. Wish you good health!
