First Response Ovulation predictor Kits

On FertilityTies.com there is always debate and guess work as to what is a TRUE +OPK.

This cycle we used the First Response 20 day Ovulation Predictor kits and I wanted to post the pics of what is still negative even though it may look positive. I always thought they were Positive til I got a TRUE Positive this cycle and the difference is very obvious as you will see in the pics below:

These are examples of NEGATIVE OPK's
Cycle day 8 (bottom) and cycle day 9 (top)

Also Negative cycle day 12 (top) & cycle day 13 (bottom)


This is an excellent pic of what a TRUE +++OPK should appear like

As you can clearly see in the pic above the first TRUE Positive OPK was cycle day 10(bottom) where the test line and control line where the exact same darkness then on cycle day 11(top *Day of Ovulation) you see that the test line is Darker than the control line. You will then notice again in the negative OPK results above cycle day 12 & 13 test lines are now back to being lighter than the control line

I do hope this helps any women out there struggling to determine whats what when it comes to Ovulation prediction. I also want to note that different brands give different results and not everyone gets the same response.
