The new iProven OPKs

AutomaticJoy

Is anyone using the new light green handled OPKs from iproven? They have changed the sensitivity and look. Experiences with these?

The old ones worked perfectly but now they seem to be terrible. I’ve taken them for 16 days straight (sometimes 2 or 3 times per day) and the test line has not changed in darkness at all. 🙄

Is it just me?
