Hi, I have que regarding periods delay of my wife. Her last date of period was 2 may and before that she used contraceptive tablet (ipill). After that we did pregnancy test and result was negative. And later we intimated but whenever sperm was about to release, I took it outside few moments before and every time it released outside. Now periods have not come till now. And I am afraid that has she become pregnant. Is it natural delay or because of tablet or are there any chance of pregnancy?
