clear blue advanced opk- the bain of my life can anyone help?

Mkddav sorry to hear your having issues too. I think with me I confused things by using 3 brands of opk. Previously I have "thought" I ov on day 16ish. I started with cb on day we as per instructions and I got a low. However that same day I got an almost posative with a strip test. But because was putting my hopes on the cb being peak before bd I choose to wait till next day. I went to flashy but strips still almost pos not quite. And I got my peak after 3 days of flashing on day 18. I started bd that day but I've since found out the first test in each cycle is always a low even if it's not a true low. So if you test that day and it should have said peak you will miss it. I think due to this I've messed up this month. I think they are great if you have regular 28 days cycle o on day 14 but maybe not for longer/irregular etc. Peak in day 10? Hmmm. It's a strange one. I feel like mine only went peak in day 18 as it was sick of giving me high. The day I got a peak on cb my sticks were negative!! So annoying lol why do we do it?

Wow, I am using the CB advanced for the first time (pink sway) and if I had known people had such issues I never would have bought it. It was on clearance, but still $30 and tax!
I normally would get a positive opk day 14 and O day 16. I started using the CB yesterday, day 9, with fmu as the instructions recommend. I got a low result as expected, but today on day 10 got a peak. What the what?! So frustrating.
I am doing bd every 4 days, so at least I am sure to get close to O at some point, but I hate the uncertainty. Time will tell.
Baby2016, you are not alone!

I try to spread the word but they have a bigger budget than I do (plus some people swear by it!)

It is possible to get peak on CD
10 though. That could mean you'll O on CD 12 possibly, all in normal range.

Yes, very frustrating! Oh well it will work out. The BD schedule should cover all possibilities so I'm trying not to dress about it.
Hopecit works out for you too baby2016!
