8dpiui positive!?

Hello, I am 8 days past <a href="https://glowing.com/glow-fertility-program">IUI</a> and have been testing out my trigger using FRER tests. I’ve had a negative every morning the past 3 days. Decided to take one tonight for the heck of it and there’s a line! With color! I know it’s early but I see it. For the record, we didn’t use progesterone and my trigger was 10 days ago. Top is this AM with FMU and bottom is tonight’s.
