Hello I've come off the pill recently and today just tried the One step Amazon opk strip for the first time. Tried following the instructions. I think I did it wrong. Rather than get a line the box seemed to go a shade of pink? Was I meant to use a cup and put it in that as I didn't? I haven't even had my first proper period yet but just wanted to see if I could work it out a bit! Thank you for any advice!
