My new OPK Theory

[tina1111]

Someone wrote in a while back about multiple pos opks 3,4 even 5 days. I found a few reasons that may happen. Well, this cycle it happened to me and I dug even deeper. I do not have PCOS, which is a reason this can happen.  Normal Lh range is 5-20. The sensitivity of OPKs ranges from 20-40ish(some are much higher, but claim to be lower) We all get fluctuations thru our cycles. Well, if you are on the normal high range, your normal variances will trigger false positives. I had 2 very definite FR opks then 3 days later had 5 very pos Answer(strip)My temps show I probably o'd the 2nd day of 2nd pos, if you're with me. lol I figure I must be on the higher end of normal and some tests are just too sensitive. Next cycle(hopefully there won't be one)I am going to do at least 3 brands per day and see what happens.

LOL tina, you are a one woman Consumer Reports!  But I thank you for doing this so the rest of us can benefit.  Hopefully this cycle you can switch your testing from OPKs to HPTs!!

I can't remember where I saw a chart of the OPK sensitivities.  But your theory makes sense.  That's why I could not imagine not BBT charting.  I have to have a way to cross-references everything.  Otherwise, I would think I was pregnant now because of all my pregnancy symptoms and stuff these last few months.
