I am 13 days past trigger & 11 days past IUI. I've been testing out my trigger and it never completely went away, but I've had faint lines yesterday & today. It doesn't seem to be getting any darker. This is my first IUI & I just don't know what to think. I don't want to get my hopes up but I'm just confused because I hear most triggers are out of your system earlier than this. Has anyone else has the trigger stick around? So nervous for this whole process & to start another IUI.
