I had a sex with my lover in January 12 after two she took a contraceptive pill so that she did get her periods in time that is January 16 but while coming to February she should get her periods on 16th of this month but still she did not get her periods. Why the periods are going to delay. Is there any chance of getting pregnancy? If the periods are going to delay due to intake of pills how many days it will takes? Could you tell me the answer as soon as possible eagerly waiting for your reply.
