BBT so confusing!!

[Marie1986S]

Hi just looking for some experience on how to read Bbt! I've hopefully attached my current cycle. Per my app it tells me I ovulated D32 (thou I think D29), however I am on D40 now and barely gettin my temp over coverline. This is only my 4th cycle temping and normally after ov my temp would raise to 36.40-36.60 in lutel phase. Just this cycle it's acting weird. P.s Temp same time every mornin when wake and opks were positive from CD29 to CD33. Have had some tingly nipples and cramping or twinges in CD34. Trying to not thing I am preg as my bbts just don't match!!
Anyone with this experience?

I'd go with CD29. I have similar this month with my bbt - bbt chart tells me I ovulated on CD12, but I can't have done going by opks, as my positive was at 9pm on CD12, and my temp rise was at 5.30am on CD13 which is less than 12hrs since start of surge. I think I ovulated CD13/14. But don't actually know. First month my opks haven't matched my bbt too. V confusing?

Also to add I have had a temp drop and bfn on 10 and 11 dpo (by my calculations of ov on cd13) but yet had awfully sore boobs which I never get plus cramping from 7-10dpo.

I guess you may have had the surge but not actually ovulated until later as seemingly temp doesn't rise until you actually ovulate. At least thou your temperature is now above the coverline if I'm reading the graph correctly, so you can be sure you ovulated. I'm still hovering about my coverL
