I am married and now it's 4th Year. We have 1 girl child and it's 2 years old. See we have sex from 3rd months of delivery. Since from I am expecting my wife get conceive for baby but not happening, so 4 months back I tested my semen strength result is good. How shall I understand is my wife using Copper T or not As once she asked to install Copper T, I said No Once I asked with are you using Coper T for that she told if you have doubt let's go doctor. Now please advise how to know that she got installed Copper T. As we never used condoms, or she not taken any pills. My semen strength also good, 1st baby is normal delivery. Always I use have intercourse with missionary position Please suggest.
