if my cycle is between 25 and 30 days, how do I calculate my cycle length?

I'm so confused.

My period usually arrives on day 25 or 26. I tracked my last 6 periods and two of them were on day 31. the others were day 25 or 26.

According to My Monthly Cycles, i should O today, but my various (yes, various) OPKs have all been negative-even the digital!

I'm so confused.

(wait,I said that already!)

When are you testing with the OPKs?

Unless you're using the CBEFM you should be testing in the afternoon after holding your pee for a3-4 hours. You might be missing your surge.

What CD did you start testing?

I've been using FMU--is that a no-no?

So many rules! The first time I got pregnant it was "hey, let's see what happens!"

Now I feel like I wasted so much money! OPKs are $$$$$$$$$$$$$$$.

Arrrggghhhh!

(Is the CBEFM that expensive monitor?)

Thanks for your help

i used the first response OPKs in the past and with that i always tested around 5pm. i always tried to hold my pee in for about 2-3 hours.

OPKs are expensive! and with my crazy cycles i could use a pack of 7 and still not get a positive reading...it was starting to annoy me so i went to temping. less expensive and clearly shows when you O. from what i hear you can get positive readings on OPKs and still not O or never get a positive OPK and still O!
