Hey sorry this is my first time using opk. Just bought a box of "mom med" ones from Amazon and I'm finding them a little confusing.
On the days I can see only one clear line I KNOW they are negative, but from CD14 onwards I can see 2 lines.
According to the instructions this could mean a positive if both are strong or the 2nd test like is strong, But it could also mean a negative???
I'm pretty sure cd 18 is positive but what about the other days would you say they are negative or positive?
I totally get why now people pay the extra for clear blue smileys!
