I was inserted a Copper T a year back, and my periods were regular since then. However, it has been more than 50 days now since I had my last period. I have a doubt, whether I have got the pregnancy, as I checked with the Pregnancy test card which is showing positive. Pls let me know, is there a posibility of the PT card show a error result? or the Loop (Coper-T) might have disfunctioned?
