BBT apps keep changing my O date - help?

(This is a long read, sorry in advance! lol)

I'm so confused on when I actually O'd this month. I use BBT, OPKs, CM, and CP to help determine my potential O date. I have a cycle length that averages 35 days, with AF lasting about 3-4 days each time.

I was sick with bronchitis for a large portion of the month, hence rocky temps. Cold meds and fevers really screwed me up!

The problem is that my OPKs predicted ovulation on or around CD17, as did my CM and CP. You can see from my chart (below) that I showed signs of fertility around then, too, such as CP SHO and fertile CM.

Despite those signs, the BBT apps I've been using keep telling me I O'd on CD 23 or 24. You can see on the chart that the fertile signs stopped, cervix closed, CM changed too. So it doesn't make sense to me that I'd O on that day when all the signs indicated it was 5 or 6 days earlier.


Now I'm trying to determine when to actually take an HPT. Should I test tomorrow, which would be 14dpo using CD17 as my O date? Or do I wait another week and test based on the suggestion from FF and C2P?

And how do I track symptoms or keep an eye out for signs of implantation? Today my CM is abundant, CP is VERY soft, medium to high, and closed. Some forums say that's a good sign for pregnancy IF it occurs after 10dpo, but if I go by my BBT I'm only 7dpo today. UGH!

I'd appreciate your thoughts/feedback on this issue!

Here's my chart so far, which starts on CD1 and goes to CD30:

It sounds like if you give yourself 2-3 more days to test, that would be best. I don't know what cp means (I am guessing cervix position???) but that is hard to determine. I thought I had all those things last month and was even late on my period by 4 days which by my count as well as what was predicted should have meant a bfp... most cheapie tests will detect hcg as early as 5 days before your missed period. I don't typically test that early because i have a range of dates my period could start.

Thanks for your feedback, cutestuff.

Anyone else care to give me their two cents? Especially if you're someone who's been charting a while, and/or who's familiar with FertilityFriend and some other BBT tracking apps?

I'm interested to see if anyone else has the same problem with Moving Ovulation. Haha
