Good Morning Madam ... My wife's periods got delayed by 2 weeks as of today. We have also checked the home pregnancy test twice and here is the result : 1. First time, there was no line in the device and when we check again next day a very thin faint line showed on the device. 2. To cross check once again, tried with other company device, no faint line seen even after 2 days. Can you please let us know the reason for delaying the periods ? NOTE : We are using birth control mechanism (copper t).
