I am sure this has been discussed at length on here, but I can't find any good threads, so here goes:

How do you experience OPKs? Do they fade in before a +? How many days do you get a +? Which type of OPK do you use? What time of day do you test? Have you ever missed your surge with OPKs?

I am turning into a completely neurotic TTCer this cycle. My cycle was really regular pre-baby and this is my first real cycle off BCP TTCing #2. Yesterday or today would be O day based on my part super regular cycles, and I have had all the O signs (CM, CP, O pains, etc.), but no positive OPK. It was almost + yesterday, but very very negative this morning. Like I said, I am being completely neurotic, but I would love to hear your experiences.
