CD10: What's up with shitty LH sticks?

I've been POAS again...but this time it's to find my LH surge so I can start counting the days til my next endo biopsy. I think that I've got to get the sample taken 11 days after my LH surge...something I'd better figure out in a hurry here!

I had 3 fancy pee sticks leftover from last month. You know, the hard plastic ones with the windows just like the HPTs (they're made by Inverness if that's any clue). I've done three of these, and according to the one I peed on at CD8, I had my surge on CD8.

That is nonsense.

Sheer nonsense.

I'm on a 27 day cycle. Sometimes 28. I don't have a luteal phase defect...and my charts show a BBT surge at the appropriate day.

Last cycle I used these fancy ones by Inverness alongside another brand. A cheap box of "Answer" brand LH strips. Because you get 20 strips to a box, I didn't squirm about doing 2 of them a day to catch that ever elusive surge.

Well last time the cheapo strips from Answer were the ones that caught my LH surge.

When I saw today that CD8 had the darked LH line in the last 3 days, I said, "WTF?" and I ran out and got me-self another box of the Answer strips. I should be surging tomorrow or the next day...maybe even CD13, but my gosh, CD8? What is wrong with these things?

It is so frustrating when we're told to use a $22 box of strips in order to take a $459 test, not counting shipping or the doctor's fee for the biopsy. You'd think they'd get this LH stuff down. It's all rather unsophisticated, this LH testing, in light of how much we are spending on the subsequent tests.
