Boots OPK Strips

[sunshinecitrus1]

I usually use Clear & Simple OPK strips which have always been pretty accurate for me. I couldn’t get any more this cycle, they were out of stock and only had a few left so purchased a couple of boxes of Boots own OPK strips. Tonight I tested with both brands with the same sample and I now have a positive Boots one and a negative Clear & Simple one! We’re TTC and I was hoping we could try tomorrow evening instead of tonight because OH is due home late but I don’t want to miss the window either! I’m on CD12 and I usually ovulate between days 14-16. Does anyone have any experiences with these two brands?

I don't know the other but the boots is 5 mins and it says 10 mins on the clear and simple, could it be it hadn't darkened yet?

@Howeverfar Both tests had been sitting there for the required time, I just think the Boots one may be more sensitive to picking up on the surge as the Clear & Simple one gave me a positive this morning.
