question: Hello doctor,I had sex with my fiancee on 21st and as a precaution, I gave her Unwanted 72 on 23rd. She got little bleeding which was thick on 4th and it continued till 8th. Now, she was expecting period again on the 4th this month, but it did not come, and therefore she took a pregnancy test on 7th and that was negative. When will she get her periods? Is there any problem?
