Maybe I'm crazy, but I also feel like cd29 is a legit option for O day with a random drop on 2dpo. That would put you at 12dpo. It'd still give you good timing, too.
I'm thinking 10 DPO is right. Only because the 3 temps after were above your O temp. Which also, could mean you tested too early... Good luck!!!
TTC 19 months ~Started RE in March 2014~ DH was not ready for IUI so we waited ~Started acupuncture in May 2014~ ~~BFP 7/6/14~~~EDD 3/14/15~~It's a girl!!~~
I guess I'm in the minority, but I don't see clear ovulation yet. Sorry But if you really think you did ovulate based on other indicators, I could maybe see 7dpo.
