Well I've been testing and it is not getting darker. I'm 12 days posrvtrigger ( well 12.5) and 11 dpo and this is at 14 mm with FMU. I think I still see a faint shadow. Am I nuts? I'm hoping the line is coming back, stronger. Last night I had a weird stitch like pain in my uterus all evening. Not painful just there, so I got excited. Anyone?
