How accurate are the Clearblue Ovulation sticks?

Question

Do they ALWAYS work?

Answer 1

if done right, pretty much yes. but it is also very easy to miss a positive especially if you only test once a day

Answer 2

it depends if you use them correctly.the best time to do one is after lunch up to 8 pm.ater you have a drink ,go to the loo,then wait 2-3 hours and test with that urine.if you do that then the tests should be accurate.i notice that a couple of days b4 i get a possitive opk,the line appears very faint.
