Well today I caved and bought 2 boxes of 30 one step brand ovulation strips.the reviews on them were decent. Can anyone shed some light on wether or not they work? They were only $5 so I'm not going to complain too much if they suck lol. I bought them because I have such a sinking feeling AF is going to show just as she always does.
