###Human: Why is there no withdrawal bleeding after taking Unwanted 72? ###Assistant: Hello. It is not always necessary to have withdrawl bleeding after taking Unwanted pill. Some women do not experience that. You should wait for your regular cycle date which might also get a little bit delayed due to intake of pill and if you missed your periods only then you have to do a pregnancy test. Otherwise, if periods start there is no need to go for it. You just relax and calm down. These pills are quite effective in preventing against pregnancy and your periods might start around 3rd or 4th of next month hopefully.
