2 big peaks two days apart- which one is ovulation?

Question

So it looks to me like I ovulated on CD14 but this chart is saying CD16. Considering that the tiny dip in between the bigger jumps wasn’t much of a dip and didn’t go lower than any pre-ovulating temps, wouldn’t that just be a part of the normal variation of temp within luteal phase?

Answer

Thank you for the advice! I recently read an article of a multi-site study which documented that initial rise of LH was a much closer approximation of ovulation day than that of LH peak. Although a combination of recorded symptoms provide the best guess of ovulation, I think based off the research I have found, the abnormal temp was the low CD16 rather than the high CD15. I started getting darker LH lines building up to CD14, but did not count the test as positive until CD14, my peak LH day. Combined with the temperature jump on CD15 and a tapering off of LH starting on CD15, I think ovulation occurred on CD14. The link to the study I found is below- it was very interesting and provided a lot of insights about how to best predict ovulation. One of the major findings was that initial rise in LH was more closely associate with actual ovulation than the LH peak which occurs more than one day after ovulation in about 1/4 of the women in the study!

Answer

One day can be off for lots of reasons. It's the overall pattern you want to look for. I'd say yes you ovulated and everything looks good :)
