testing out the trigger shot

Marissa
Hi ladies I am now 10dpiui and 11 days since my trigger shot. Yesterday I got a faint positive in the afternoon, this morning the same only a little more faint. This is my first <a href="https://glowing.com/glow-fertility-program">IUI</a> after trying for two years and the only new symptom I can say I have is cramping ( very uncomfortable ) has this ever happened to anyone? Did you end up with a positive blood test or negative? 
Also I have heard the trigger shot can stay in your system as long as 14 days!? Is this true
