Possible to miss ovulation using OPKs?

Question

This is our 3rd month TTC and I decided to use OPKs for the first time because I found Clear Blue digital tests expiring and on sale for 1/2 price (expiring may 2015).

I have a fairly regular 26-29 day cycle and usually get EWCM around ovulation which I haven't really had.

I'm now on cd 15 and I haven't received a + test yet. Is it possible that I missed ovulation? Did I not ovulate (yet)? Are the tests faulty? What do you think?

Extra info: I travelled to an 11hr time difference for last week and 1st week of this cycle and had a yeast infection after my period which I treated with a 1-day tablet around cd 11. I've been testing every morning with fmu. Worried that we aren't conceiving be I'm not ovulating.

Answer

CB Digital showed positive for me the week before last but FROPK and Wondfo both said negative. On a whim I decided to try CB again last week...positive again but this time so were FR and Wondfo. Moral of the story...digital isn't always accurate. I recommend getting cheap test strips to compare with digital. 😉

Answer

FMU might be the issue. You're supposed to test later in the day because LH (the hormone the test reacts to) isn't at it's highest in the morning. I was told to test between 10-3.

Answer

I'd like to know as well! I used OPKs the past three months and the first two months I got a positive on CD 14 and this month it's CD 17 and still no positive!  I use FMU every time and even if I get up to pee in the middle of the night I don't test until I've held it four hours. I really hope I didn't miss it - and worse because glow keeps changing my period start date as a result so I will have no idea when my period will be late gahh!

Answer

I only got my peak on day 16, others have had their peak at dats 16-21, so it could be a late ovulation date. I also just found out that we sometimes don't ovulate every month, so maybe it hasn't happened this month.
