Testing with OPKs

So, I'm at the point in my cycle where I am going to begin testing with OPK's again. My last 2 cycles were 25 and 29 days. I only tested with OPK's during the last cycle. I tested from CD 8-CD13 last cycle, and never got a positive opk, and kind of gave up because I was freaking myself out. Since my cycle was longer this time than last time, I'm just going to assume that I O'd past CD 13, and thats why I never got a positive OPK. However, I was reading somewhere that LH usually starts in the late morning- and thats when you should test. They said if you test with FMU, every morning, that you could miss your surge.

What do you guys think about that? Also, when does everyone test?

Thanks so much!

I was told to test between 12pm-8pm. Sorry, that is all the info I have

Re: Testing with OPKs

Test between 12-8pm, test 2x a day if you feel more comfortable about it (I did this bc I was worried I'd miss my surge).

As you get closer to Oing you should notice more CM, this means your body is preparing to O. (CM will dry up after Oing). If you notice your CM and test when you start having more of it you should catch your surge.
