@smores:  As I used OPKs for the first time this month and did not get a positive, all I can say is what I’ve heard: That people have a hard time until it’s positive, when it’s positive, they know it’s positive. If that makes sense. Pic? Here’s my questionable positive.

I found it hard too, so when I think I have a positive I use a clearblue digi to confirm. They are a bit expensive but I found it helped me have peace of mind.

I use Clearblue Digital OPKs.  You either get a blank circle or a smiley face.  They say in the instructions that you can’t tell anything from any lines you see on the test (after ejecting the stick part, you can see a control line and another blue line. I have however, noticed that there is a faint blue line when the test is negative, and that it is as dark as the control line when the test shows positive.  So I would GUESS that it’s a positive test on the types of strips you’re using when the lines are the same color.  The PP’s idea of using a digital test to confirm when you think you have a positive is a good idea.

This is my personal go-to pic for telling the difference between pos. and negative OPKs. Only the bottom one is positive. Hope it helps!

Exactly what ChuckNorrisFTW said. I did those 2 months (not trying yet but was trying to figure out how my body feels when I am ovulating) and the 1st month I felt like several *could* have been positive until the next month when I had a total obvious one. My problem was I get a lot that are similar to the control line but when you have a positive you know it.

When you think you are getting close, try also testing with FMU.  That was the only way I was ever able to get a + OPK (in 13 cycles…).

As for your second question, most of the time I O’ed the day after my last + OPK (I would get 2-3 days of + tests each cycle), but some cycles I O’ed the day of my last + OPK, and a few freakish months I got a strong + the day after O.  (O confirmed by temps, CP, and CM.)

@smores:  others have already said it – but once you get one, you’ll know!! and you’ll wonder how you were ever confused before 🙂

also, mine often get darker and lighter before a positive OPK, this doesn’t neccessarily mean you missed it, LH varies during your cycle. not that everyone catches their surge.

For the moment, I’d keep testing, especially if you’ve got cheapies that you’re not too worried about wasting…
