Advice please

So this is our first month of back to ttc naturally after having 3 failed rounds of <a href="https://glowing.com/glow-fertility-program">ivf</a> over the past year. Only CD 6 but I’ve got the clear blue monitor that told me to do opk today, obviously it is low but I also did a cheapie as I want to compare them and I was wondering if it was normal to get no 2nd line at all?
