No. There is not. The only thing that makes a pregnancy test show positive is a hormone known as HGC. In the reverse if a pregnancy test shows negative it means there is too little of a reading of HGC levels, 25hgl, or lower in your blood. The hormones in birth control have nothing to do with the hormones a pregnancy test reads. Hope this helps.
