How long does it take for your opk to stop showing positive. My pregnancy test strips are now showing negative. I lost my baby at 9w2d when I was suppose to be 12wks. I'm ready to start trying again. My first two times ever getting pregnant in 8 years and I've lost both. The first at 6 wks in May, then again in October.
