Hello-I am hoping to go in for my first <a href="https://glowing.com/glow-fertility-program">IUI</a> next weekend and will start my opk tomorrow. A few months back I was testing and after a few days I got an error on the display (clearblue digital advanced)  so could not keep testing using that base. I am anxious that will happen again this cycle so thinking of using 2 kits. I am concerned it could get confusing and that I might get conflicting results. Any advice on this one? Thanks!
